refactor(studio): migrate telemetry to useTrack (#46140)

## Summary

I migrated every `useSendEventMutation` call site in `apps/studio` to
`useTrack`, deleted the legacy hook, and added a lint guardrail so it
can't return. `useTrack` is the type-safe replacement: it auto-injects
`groups: { project, organization }` from the selected project/org and
types `action` + `properties` against `TelemetryEvent`. Existing call
sites built groups manually and were not type-checked at the action
level. The migration covers 81 files (60 trivial swaps, 9 org-only, 3
pre-auth, 5 bespoke, 4 test mocks).

## Changes

- Migrated trivial call sites across `pages/project/[ref]`,
`components/interfaces/*` (Reports, Storage, Realtime/Inspector,
SQLEditor, Functions, EdgeFunctions, Integrations, ProjectAPIDocs,
Branching/BranchManagement, TableGridEditor, Connect, Docs, Auth,
Support, Home, ProjectHome, App), `components/layouts/*`, and
`components/ui/*`.
- Migrated org-only sites (`Organization/Documents/*`,
`Organization/BillingSettings/Subscription/*`,
`Organization/SecuritySettings.tsx`,
`Account/Preferences/DashboardSettingsToggles.tsx`) by dropping the
manual `groups: { organization: ... }` and letting `useTrack`
auto-inject. Verified `useSelectedProjectQuery` is disabled on org
routes (gates on URL `[ref]`).
- Migrated pre-auth sites (`SignInForm.tsx`, `sign-in-mfa.tsx`,
`profile.tsx`) where neither project nor org is resolved.
- Bespoke handling:
- `execute-sql-mutation.ts` and `table-row-create-mutation.ts`: pass `{
project: projectRef }` via `groupOverrides` since the mutation can
target a non-selected project ref.
- `useStudioCommandMenuTelemetry.ts`: kept a direct `sendTelemetryEvent`
call because studio groups must override pre-built event groups
(opposite of `useTrack`'s override direction).
- `AIAssistantOption.tsx`: passes sentinel-aware `groupOverrides` so
`NO_PROJECT_MARKER`/`NO_ORG_MARKER` continue to suppress group emission.
- `SidePanelEditor.utils.tsx`... (continued)
