## What kind of change does this PR introduce?

Docs update (JSDoc comments only in the telemetry catalog — no runtime
code, event names, or property types change).

## What is the current behavior?

In `packages/common/telemetry-constants.ts`:

- **Before:** The catalog only documented branch deletion as happening
from the branches page. `branch_delete_button_clicked` listed a single
`@page` of `/dashboard/project/{ref}/branches`, even though the button
also fires from the merge page and from project Settings > General.
- The `sql_editor_autosave_disable_clicked` event's `@page` read
`/project/{ref}/sql/{id}`, missing the `/dashboard` prefix used by every
sibling SQL-editor event.

## What is the new behavior?

- **After:** `branch_delete_button_clicked` now documents all three
surfaces where the button fires — the branches page, the merge page, and
project Settings > General (`/dashboard/project/{ref}/branches,
/dashboard/project/{ref}/merge or
/dashboard/project/{ref}/settings/general`).
- `sql_editor_autosave_disable_clicked` now uses
`/dashboard/project/{ref}/sql/{id}`, consistent with the other
SQL-editor events.

## Additional context

**How:** Both changes are `@page` JSDoc edits in
`packages/common/telemetry-constants.ts`, touching the JSDoc blocks for
`BranchDeleteButtonClickedEvent` and
`SqlEditorAutosaveDisableClickedEvent`. The multi-page format mirrors
the comma/"or" style already used by other multi-page events in the same
file. The Settings > General call site was added in #47677
(`apps/studio/components/interfaces/Settings/General/DeleteBranchPanel.tsx`);
the merge-page and branches-page call sites are in
`apps/studio/pages/project/[ref]/merge.tsx` and
`apps/studio/pages/project/[ref]/branches/index.tsx`.
