- Created api-helpers.ts with shared getAccessToken() + createNotesApiClient()
- Removed duplicate API client factory from notes-client.ts, review-client.ts,
saved-views-client.ts (3 copies → 1 shared module)
- Added reviewedBy/reviewedAt/reviewNote fields to review-client NoteAgentActionDoc
type to match backend response shape
- Search page: use crypto.randomUUID() for saved view IDs instead of Date.now()
to prevent collisions on rapid saves
Verification: web typecheck + 6/6 tests pass.
