refactor: centralize writings fetching in controller

- Remove incremental loading (since filter) from writingsController
- Fetch ALL writings without limits for complete results
- Remove duplicate background fetch from Me.tsx and Profile.tsx
- Use writingsController.start() in Profile to populate event store
- Keep code DRY by having single source of truth in controller
- Follows controller pattern: stream, dedupe, store, emit
