refactor(serializer): avoid generic catch for invalid query

* fix(copy-button): use focus-independent clipboard copy

navigator.clipboard.writeText requires document focus and rejects with
"Document is not focused" in remote-desktop/VDI/multi-monitor setups.
Copy through react-use's useCopyToClipboard (execCommand) via a colocated
useCopyButton hook that also owns the transient "copied" state.

Fixes SIGNOZ-UI-5J4

* refactor(legend): reuse CopyButton for the copy action

Replace the duplicated inline copy button with the shared CopyButton.
Each button now owns its own copied state, so the per-item id tracking
is no longer needed.

* chore(hooks): remove unused useCopyToClipboard hook

No longer imported after CopyButton and the legend moved to
useCopyButton.

+# AuthZ Guide
+
+How to structure a page so it works with the permission system.
+
+We are migrating from the `ADMIN | EDITOR | VIEWER` roles to per-action checks. Instead of granting `VIEWER` and
+exposing everything, a user can now be granted access to a single resource, eg: `Logs` only.
+
+- [Prerequisites](#prerequisites)
+- [Core rules](#core-rules)
+- [Page patterns](#page-patterns)
+- [What "blocked" means](#what-blocked-means)
+- [Migration checklist](#migration-checklist)
+- [Testing](#testing)
+
+## Prerequisites
+
+Check whether the resource your page represents is supported: see
+[permissions.type.ts](../src/lib/authz/hooks/useAuthZ/permissions.type.ts) for the current resources and their allowed
+verbs.
+
+**If the resource is not listed there, skip authz for now**. The backend does not enforce it yet, so any frontend
+check would be decorative. Revisit once the resource is generated into that file (it is auto-generated from the
+backend).
+
+## Core rules
+
+These hold for every page. The per-pattern sections below only add to them.
+
+1. **A page is always reachable, regardless of permission.** The intended action must be known before permission can
+   be checked, so the route renders first and individual pieces are gated.
+2. **`update` requires both `read` and `update`.** A user who can write but cannot read the current value must not get
+   an edit affordance.
+3. **`delete` is independent of `read`.** Delete controls stay visible for a user who holds `delete` but not `read`.
+4. **Never gate per row.** If a user can `list`, render every row. Check `read` only when the row is opened (drawer or
+   detail route).
+5. **Gate the narrowest thing that works**, a button over a section, a section over a page.
+6. **A resource may be gated while a sub-resource is not.** A user without `read` on Service Accounts can still hold
+   `create` on API Keys, so blocking the outer container would hide work they are allowed to do.
+7. **Verbs not covered here** (`attach`, `detach`, `assignee`) behave like `delete`: gate the control that triggers
+   them, not the surrounding content.
+
+## Page patterns
+
+### List page
+
+![Visual rules for structuring a list page](./assets/list-example.svg)
+
+Without `list`, but with any of `read` / `create` / `update`, only the table is blocked:
+
+- Title, description, search filters and action buttons stay visible.
+- Filters and any control that drives the table are non-interactive.
+- The create button stays enabled if the user holds `create`.
+
+### Edit page
+
+![Visual rules for structuring an edit page](./assets/edit-example.svg)
+
+Without `read`:
+
+- Block the content with `withAuthZContent`, not the whole route.
+- Keep delete visible (rule 3).
+- Keep update blocked (rule 2).
+
+### Drawer
+
+![Visual rules for structuring a drawer](./assets/drawer-example.svg)
+
+Without `read`:
+
+- Block the drawer body, not the drawer itself.
+- Prefer routing that carries the resource ID in the URL, so delete stays reachable without `read`.
+- Keep update blocked (rule 2).
+- Watch for sub-resources the user may still be allowed to act on (rule 6).
+
+### Create
+
+Without `create`:
+
+| Entry point           | Gate with                                                     |
+| --------------------- | ------------------------------------------------------------- |
+| Button                | `AuthZButton`                                                 |
+| Dedicated create page | `withAuthZPage`                                               |
+| Create drawer opened directly (deep link) | `withAuthZContent` on the body + `AuthZButton` on footer actions |
+
+### Delete
+
+Gate the control with `AuthZButton`, or `AuthZTooltip` for a non-button trigger such as an icon or menu item.
+
+### Quick filters
+
+![Visual rules for structuring a page with quick filters](./assets/quick-filters-example.svg)
+
+## What "blocked" means
+
+Blocking is always a visible denial, never a silent removal. Use the components in
+[`lib/authz/components`](../src/lib/authz/components/README.md) rather than hand-rolling a check, they carry the
+denial message and the loading state.
+
+| Scope           | Component                                 | Denied state                                |
+| --------------- | ----------------------------------------- | ------------------------------------------- |
+| Button          | `AuthZButton`                             | Disabled + tooltip                          |
+| Any element      | `AuthZTooltip`                            | Disabled child + tooltip                    |
+| Section         | `withAuthZContent` / `AuthZGuardContent`  | Inline `PermissionDeniedCallout`            |
+| Page / route    | `withAuthZPage` / `AuthZGuardPage`        | `PermissionDeniedFullPage`                  |
+| Custom fallback | `withAuthZ` / `AuthZGuard`                | Whatever you pass as `fallback`             |
+
+Prefer the HOC (`withAuthZ*`); reach for the JSX guard (`AuthZGuard*`) when the gate depends on conditional rendering
+and an HOC cannot express it. The components README has the full decision tree and how to build the `checks` array.
+
+## Migration checklist
+
+Use the existing components. Create a new one only if none fit.
+
+- [ ] Can I apply a `withAuthZ*` variant directly, or must I extract the content into a component first?
+  - If extraction is needed, declare the new content component in the same file to keep the diff small, then move it
+    to its own file in a follow-up commit or PR.
+- [ ] Is the layout structured to respect the [core rules](#core-rules)?
+  - If not, raise it in the frontend Slack channel before reshaping the page.
+- [ ] Am I gating a shared component rather than a page or section?
+  - If so, it must stay functional with no permission. Example: the Query Builder works without field suggestions when
+    the user cannot read them.
+
+## Testing
+
+### Devtool
+
+Press `Cmd + K` (`Ctrl + K` on Windows/Linux) to open the shortcuts, search for `AuthZ`, and pick the first
+result. The devtool simulates granted and denied permissions across the UI.
+
+Available only in local development, it is stripped from production builds.
+
+### Unit tests
+
+[`lib/authz/utils/README.md`](../src/lib/authz/utils/README.md) covers the `*.authz.test.tsx` naming convention, the
+MSW handlers (`setupAuthzAdmin`, `setupAuthzDenyAll`, `setupAuthzDeny`, `setupAuthzAllow`,
+`setupAuthzGrantByPrefix`), and how to test the loading state.
