fix(events): Convert events NocoDB client from v1 to v2 API

- Updated all NocoDB API calls from v1/db/data/v1/ to v2/tables/ endpoints
- Fixed 422 Unprocessable Entity errors on events calendar page
- Ensures consistency with members system which already uses v2 API
- Updated methods: findAll, findOne, create, update, delete, createRSVP, findEventRSVPs, findUserRSVP, updateRSVP, updateAttendeeCount, findUserEvents
- Maintains same functionality while using correct API version

Resolves continuous 422 errors when loading events calendar.
