Add Meilisearch event indexing with 3 indexes: global, admin, per-account

- Create EventIndexService with indexEvent() and removeEvent()
- event_global: online events where isSecret=false (public search)
- event_admin: all events regardless of status (admin search)
- event_{accountId}: all events per organizer (account search)
- Integrate indexing in create/edit/delete event controllers
- Try/catch for Meilisearch unavailability (graceful degradation)
- Add 5 unit tests for EventIndexService
