feat(dashboards): add the heatmap chart layer

Bucket × time density grid drawn on canvas through uPlot hooks: columns are
time slices, rows are bucket ranges, and cell colour is the observation count,
so a distribution can be watched changing shape instead of collapsing to
percentile lines.

- renderer, palettes and DOM hover overlay under lib/uPlotV2/plugins/HeatmapPlugin
- bucket axis places log10 values on a linear uPlot scale, extending
  symmetrically when the boundaries include zero or negatives
- `null` (no data) renders hatched and is never conflated with a `0` count
- purpose-built tooltip: neighbouring buckets, or per-group contribution when
  the cell sums more than one group
- ColorBar scale key, reusable by other density visualisations
- group legend through the shared Legend, isolate on label / exclude on marker

The chart takes bucket bounds plus per-group series and pivots them itself.
Panel kind, spec and the `heatmap` request type land separately.

-  - `fixtures/alerts/alert-rules` — worker-scoped rule list + test-scoped rule factory
-  - `fixtures/alerts/alert-history` — extends alert-rules, adds history fixtures (waits on ruler evaluation)
-  ```ts
-  // Alert list tests - need rules, no history
-  import { test, expect } from '../../../fixtures/alerts/alert-rules';
-  
-  // Alert history tests - need evaluated history rows
-  import { test, expect } from '../../../fixtures/alerts/alert-history';
-  ```
 - **Test titles:** `TC-NN <short description>` — matches the planner's IDs.
 - **Self-contained state.** The bootstrap creates a fresh stack with **zero** dashboards / alerts / etc. — never assume pre-existing data. Two cleanup shapes are valid; pick based on the spec size:
   - **Per-test `try / finally`** — small specs (~ <10 scenarios) where each test owns its data.

 - **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.

 | `SIGNOZ_E2E_SEEDER_URL` | Seeder HTTP base URL — hit by specs that need per-test telemetry. |
 
-Precedence in `playwright.config.ts`, lowest to highest: `.env` (user-provided, staging) → `.env.local` (bootstrap-generated, local mode) → whatever is already in `process.env`. The config parses both files itself and only fills in keys the environment does not already define, so exporting a variable always wins:
-
-```bash
-# runs against a locally served frontend, not whatever .env.local points at
-SIGNOZ_E2E_BASE_URL=http://127.0.0.1:3301 pnpm test tests/alerts
-```
-
-This is deliberately not `dotenv.config({ override: true })`. That flag makes the *file* beat `process.env`, which silently discarded exported values — including the `SIGNOZ_E2E_BASE_URL` in `pnpm test:staging`, whenever a `.env.local` happened to exist.
+Loading order in `playwright.config.ts`: `.env` first (user-provided, staging), then `.env.local` with `override: true` (bootstrap-generated, local mode). Anything already set in `process.env` at yarn-test time wins because dotenv doesn't touch vars that are already present.

  *
  * **Pagination shows "Auto" option** when `calculatedPageSize` is passed, allowing users
  * to reset to auto-calculated size.
- *
- * **`setPage` accepts history options**: `setPage(page, { history: 'replace' })` rewrites the
- * current history entry instead of pushing a new one. Use `replace` for corrections the user
- * did not ask for — otherwise the back button walks straight back into the state that was just
- * corrected. Only applies when the page is synced to the URL; local (non-URL) pages ignore it.
- *
- * @example useRecoverFromEmptyPage — send the user back to a page that has data
- *
- * When rows disappear underneath the current page (filters narrowed, time range moved, items
- * deleted), the user is stranded on an empty page they cannot leave by scrolling. This hook
- * watches the fetched result and corrects the page with `history: 'replace'`, so the back
- * button does not return to the empty page.
- *
- * Correction rules:
- * - `page < 1` → jump to page 1, even while fetching or disabled. Such a page usually maps to a
- *   negative offset the API rejects (400 `offset cannot be negative`), so the response can never
- *   confirm the page is empty — deferring to it would strand the user on a permanent error.
- * - Page is empty and not page 1 → go to `min(ceil(total / pageSize), page - 1)`. When `total`
- *   is trustworthy that lands on the last page holding data; when `total` is unknown or zero it
- *   lands on page 1; and when `total` claims this page should have had rows it steps back a
- *   single page. Repeated step-backs give up and jump to page 1 after the second one, so a
- *   badly inflated `total` cannot walk the user down one request at a time.
- * - Page has rows, or the user is already on page 1 → do nothing (an empty page 1 means there
- *   is genuinely nothing to show).
- *
- * Pass `isFetching` so the hook waits for the request to settle, and `isDisabled` so a failed
- * request is not mistaken for an empty page. Neither gate suppresses the `page < 1` clamp.
- *
- * ```tsx
- * import { useRecoverFromEmptyPage, useTableParams } from 'components/TanStackTableView';
- *
- * const { page, limit, setPage } = useTableParams(QUERY_PARAMS, { page: 1, limit: 20 });
- * const { data, isLoading, isFetching, isError } = useListQuery({ page, limit });
- *
- * useRecoverFromEmptyPage({
- *   page,
- *   pageSize: limit,
- *   rowCount: data?.rows.length ?? 0,
- *   total: data?.total ?? 0,
- *   isFetching: isLoading || isFetching,
- *   // Skip correction on errors — no rows there means "request failed", not "page is empty".
- *   isDisabled: isError,
- *   setPage,
- * });
- * ```
