claude[bot] 62fe0fca4a fix(studio): guard branches and read-replicas queries against non-array 200 bodies (#50347)
## Summary
- `getBranches()` (`apps/studio/data/branches/branches-query.ts`) and
`getReadReplicas()` (`apps/studio/data/read-replicas/replicas-query.ts`)
cast the raw API response body to an array with no runtime check.
- When the endpoint returns a defined-but-non-array 200 body, the `??
[]` fallback in each consumer doesn't catch it (the value isn't
nullish), and the first `.find`/`.filter` call throws, crashing the
whole page via `globalErrorBoundary`.
- This is the same known class of bug already fixed elsewhere in the
codebase (e.g. `apps/studio/data/lint/lint-query.ts`, and the
`api-keys`/`oauthApps`/`secrets` fetchers) — applies the same
`Array.isArray(data) ? data : EMPTY_ARR` guard.

## Evidence (Sentry, past week)
- [SUPABASE-APP-KA2](https://supabase.sentry.io/issues/7722780387/) —
`(m??[]).find is not a function` in `ActivityStats.tsx`
(`branchesData.find`), full-page crash on `/dashboard/project/[ref]`.
- [SUPABASE-APP-KAE](https://supabase.sentry.io/issues/7729679561/) —
`u.filter is not a function` in `AWSPrivateLinkForm.tsx`
(`databases.filter`), full-page crash on
`/project/[ref]/settings/integrations`.

## Test plan
- [ ] Existing query hook tests still pass
- [ ] Manually verified `Array.isArray` guard mirrors the established
`lint-query.ts` pattern
