feat: add spec for text panel

#### Description

- Changes `GET /api/v1/features` from `ViewAccess` to `OpenAccess` in
both editions so every authenticated user, including those on custom
roles, can read feature flags.
- Feature flags describe the org's plan, not the caller's privileges,
and the frontend needs them to boot. With #12700 making the active
license readable by every authenticated user, the flags must be readable
too — otherwise custom-role users load the license but hang on the flags
fetch.
- Applies the same change to the flagger endpoint `GET /api/v2/features`
so the v2 client behaves identically when the frontend migrates to it.

 - **The list pages render zero-state when the workspace is empty.** Many locators (search input, sort button, `new-dashboard-cta` testid, "All Dashboards" header) are absent in zero-state. A 30s timeout on those usually means the workspace was empty — seed first via `createDashboardViaApi`.
 - **The "Enter dashboard name…" inline field is a `RequestDashboardBtn` (template-request feedback form), not a create flow.** Tests that try to use it to create a named dashboard will silently no-op. The only UI create paths are the "New dashboard" dropdown → "Create dashboard" (default name "Sample Title", see `DEFAULT_DASHBOARD_TITLE`) or "Import JSON".
 - **Auth.** `tests/e2e/fixtures/auth.ts` logs in once per worker and caches `storageState` (cookies + localStorage with `AUTH_TOKEN`). For API-driven seeding/cleanup, use `authToken(page)` from `helpers/dashboards.ts` and pass `Authorization: Bearer <token>`. Never re-implement login.
+- **Extended fixtures.** Domain-specific fixtures extend `auth` and add seeded data. Alerts uses `fixtures/alerts/alert-rules` (worker-scoped rule list, test-scoped factory) and `fixtures/alerts/alert-history` (extends alert-rules, waits on ruler evaluation). See [docs/contributing/tests/e2e.md](../../docs/contributing/tests/e2e.md) for the pattern. When a test fails on missing data, check if it imports the wrong fixture level.
 - **Ant Design popovers** (sort menu, action menu) are click-toggle. The trigger element is often an inline `<svg>` with a `data-testid` — clicking it opens the popover; clicking it again closes. After selecting an option, the popover auto-closes. If a test interacts with the popover twice, wait for the menu items to be visible explicitly between toggles.
 - **Artifacts.** Every failed test writes to `tests/e2e/artifacts/results/<test-slug>/` — the `error-context.md` accessibility snapshot is the fastest way to see what the page actually looked like when it failed.
 - **Type-check.** After edits, run `npx tsc --noEmit -p tests/e2e/tsconfig.json` if it succeeds, or rely on `npx playwright test --list` to validate the spec parses.

 Rule of thumb: if it's a `test.extend` fixture, put it in `fixtures/`. If it's a function you call explicitly (or a constant the function uses), put it in `helpers/`. If it's a static file the helpers read, put it in `testdata/`.
 
+### Extended fixtures
+
+For features needing complex setup (API-seeded data, ruler evaluation waits, cleanup), create domain-specific fixtures that extend `auth`. Group them in `fixtures/<domain>/`.
+
+**Fixture scopes:**
+- **test scope** — fresh data per test. Use for mutations (edit, delete, rename).
+- **worker scope** — shared across tests in one worker. Use for read-only data. Worker scope pays the setup cost once per worker instead of once per test.
+
+**The alerts pattern** (`fixtures/alerts/`) demonstrates extending fixtures:
+
+```
+fixtures/alerts/
+├── alert-rules.ts   # extends auth — worker-scoped rule list + test-scoped factory
+└── alert-history.ts # extends alert-rules — adds history fixtures (waits on ruler)
+```
+
+Specs import from the fixture they need:
+
+```ts
+// List tests — just need rules, no history
+import { test, expect } from '../../../fixtures/alerts/alert-rules';
+
+// History tests — need history rows from ruler evaluation
+import { test, expect } from '../../../fixtures/alerts/alert-history';
+```
+
+**When creating new fixtures:**
+
+1. **Identify scope** — Will tests mutate the data? If yes, test-scoped. If read-only, worker-scoped.
+2. **Group by domain** — Put fixtures in `fixtures/<domain>/`. Helpers in `helpers/<domain>/`.
+3. **Extend existing fixtures** — Chain from `auth` or another fixture to inherit its setup.
+4. **Handle timeouts** — Worker-scoped fixtures that wait on backend processing need explicit timeouts.
+5. **Clean up** — Always delete seeded data in the fixture teardown (after `use()`).
+6. **Extract logic into functions** — Keep the `test.extend()` block lean; move setup/teardown logic to named functions so the extend block reads as a manifest of "what fixtures exist."
+
 Each spec follows these principles:
 
 1. **Directory per feature**: `tests/e2e/tests/<feature>/*.spec.ts`. Cross-resource junction concerns (e.g. cascade-delete) go in their own file, not packed into one giant spec.

-name: scaffold-feature
-description: Scaffold the co-located feature structure in frontend/src. Use when creating a new page, feature, view (tab), or component folder, when a feature needs a shell with tabs, or when moving existing code out of src/container into src/pages. Generates the full folder tree (components/hooks/store/types/utils/constants/__tests__/README) with one command.
----
-
-# Scaffold a feature
-
-The frontend is moving to a co-located layout (Bulletproof React / FSD): everything a
-feature owns lives in the feature's folder. Read `references/layout.md` for the full
-target structure and the rules about what may live where.
-
-**Never hand-create these folders.** Run the generator so every feature comes out
-identical, then fill it in.
-
-## Command
-
-```bash
-pnpm scaffold page <Name> [options]        # a page/feature under src/pages
-pnpm scaffold component <Name> [options]   # a component folder
-```
-
-| Option | Applies to | Effect |
-| --- | --- | --- |
-| `--views A,B,C` | `page` | Makes the page a shell with tab switching and generates one view folder per name. |
-| `--parent <path>` | `component` | Parent, relative to `src` (default `components`). A feature path like `pages/Traces/Explorer` nests the component under that feature's `components/`. |
-| `--full` | `component` | Also adds `components/`, `hooks/`, `store/`, `types.ts`, `utils.ts`, `constants.ts`, `README.md` for a component that owns children. |
-| `--no-tests` | both | Skips `__tests__/`. |
-| `--dry-run` | both | Prints what would be written, writes nothing. |
-| `--force` | both | Overwrites files that already exist (off by default; existing entries are reported as skipped). |
-
-Folder names keep the casing you type, with the first letter forced up, so
-`LLMObservability` stays `LLMObservability` rather than being re-cased. Separated names
-collapse to PascalCase: `api-monitoring` and `api monitoring` both give
-`pages/ApiMonitoring`. Test ids, headings, tab paths and constants are all derived from
-that folder name — `TracesFunnels` gives `traces-funnels-page`, `Traces Funnels` and
-`TRACES_FUNNELS_TABS`.
-
-## What you get
-
-```
-pages/ApiMonitoring/
-  index.tsx                       # the page component
-  ApiMonitoring.module.scss
-  components/  hooks/  store/     # empty, ready for the first file
-  types.ts  utils.ts  constants.ts
-  __tests__/ApiMonitoring.test.tsx
-  README.md
-```
-
-With `--views`, the root becomes a `RouteTab` shell (`index.tsx` + `constants.ts` with the
-tab definitions) and each view gets the tree above.
-
-## Examples
-
-```bash
-pnpm scaffold page ApiMonitoring                                    # leaf page, no shell
-pnpm scaffold page Traces --views Explorer,Funnels,Views            # shell + 3 views
-pnpm scaffold page Traces/Explorer                                  # one more view under an existing shell
-pnpm scaffold component DataTable                                   # global, src/components/DataTable
-pnpm scaffold component QueryBar --parent pages/Traces/Explorer     # feature-local component
-```
-
-## After generating
-
-1. **Wire the route** (pages only) — the generator does not touch shared files:
-   - add the path to `src/constants/routes.ts`
-   - add a `Loadable` lazy import to `src/AppRoutes/pageComponents.ts`
-   - add the entry to `src/AppRoutes/routes.ts`
-   - for a shell, replace the local `BASE_PATH` strings in `constants.ts` with those `ROUTES` entries
-2. **Delete the placeholders you don't need** — empty `types.ts` / `utils.ts` /
-   `constants.ts`, and any of `components/`, `hooks/`, `store/` the feature won't use.
-   Those three folders are created empty; git only picks them up once they hold a file.
-3. **Fill the README** — the generated file has the prompts; a feature folder without a
-   filled-in README is not done.
-4. **Follow the repo rules while filling it in**: `@signozhq/ui` + `@signozhq/icons` only,
-   CSS Modules (`docs/css-modules-guide.md`), React Query for server state (prefer
-   `api/generated` hooks), nuqs for URL state, Zustand for client state, `data-testid` on
-   every interactive element.
-5. **Verify** before reporting done:
-   ```bash
-   pnpm tsgo --noEmit
-   pnpm oxlint src/pages/<Feature>
-   pnpm jest src/pages/<Feature>
-   ```
-
-## Editing the templates
-
-Templates live in `templates/` — `feature/`, `shell/`, `component/` and
-`component-extras/` (the `--full` additions). Every template file ends in `.tmpl`, which
-keeps TypeScript, lint and your editor from reading them as source; the generator strips
-that suffix on the way out, so `index.tsx.tmpl` becomes `index.tsx`. Tokens are
-substituted in both file names and contents: `__Pascal__`, `__kebab__`, `__camel__`,
-`__CONST__`, `__Title__`. The shell's `constants.ts` additionally takes
-`__VIEW_IMPORTS__` and `__TAB_ENTRIES__`, which the generator builds from `--views`. The
-empty folders come from `FEATURE_DIRS` in `scaffold.mjs`. Change these, not the generated
-output, when the team's conventions move.

-## Rules
-
-- **Folder names are PascalCase**, spelled the way the feature is spelled in the product
-  (`ApiMonitoring`, `LLMObservability`). This holds for shells, views and components alike.
-- **A page folder is the unit of ownership.** Anything used by exactly one feature lives
-  inside it, however deeply nested. Promote to `src/components` / `src/utils` / `src/hooks`
-  only when a second feature needs it.
-- **`index.tsx` is the entry**, and it composes. Business logic goes to `hooks/`, data
-  shaping to `utils.ts`, state to `store/`.
-- **Nested components repeat the same shape.** A component folder may hold its own
-  `components/`, `hooks/`, `store/`, `types.ts`, `utils.ts`, `constants.ts`, `__tests__/`.
-  Nest as deep as ownership actually goes; don't flatten a component that owns children.
-- **Shell vs no shell.** A page with tabs gets a shell `index.tsx` whose only job is tab
-  switching, plus one folder per view. A page without tabs is just the feature folder.
-- **Tests.** Feature-root tests in `__tests__/`; a component's tests next to the component
-  (its own `__tests__/`). Never reach across features in a test.
-- **No barrel files.** A page's `index.tsx` is the route entry (a component), not a
-  re-export hub. Import components by their own path.
-- **File size.** Split past ~300 LOC: extract components, and behaviour into
-  `use<Component>Callbacks`-style hooks. More than ~3 type declarations in a file means a
-  `types.ts`, and more than ~3 in `types.ts` means a `types/` folder.
-- **Styling.** CSS Modules (`<Name>.module.scss`) next to the component — see
-  `docs/css-modules-guide.md`. Semantic tokens only.
-- **State.** Server → React Query (prefer `api/generated` hooks); URL → nuqs; client →
-  Zustand, one store per file, always with a selector. No Redux or Context for new code.
-
-## Migrating existing code
-
-Most feature code still lives in `src/container` and `src/modules`, with a thin wrapper in
-`src/pages`. When touching one of those features:
-
-1. Scaffold the target with `pnpm scaffold page <Name>` (see `../SKILL.md`).
-2. Move files in, one concern per commit — components, then hooks, then state.
-3. Update importers; keep `src/container/<Feature>` deleted, not re-exported. A shim
-   directory is how the old layout survives.
