fix(events): Convert NocoDB query syntax from SQL-like to v2 API format

- Updated all where clauses to use NocoDB v2 syntax: (field,operator,value)
- Changed SQL-like syntax (field >= 'value' AND field = 'value') to v2 format
- Fixed date range queries: (start_datetime,gte,date) and (start_datetime,lte,date)
- Fixed equality queries: (status,eq,active) instead of (status = 'active')
- Fixed AND/OR logic: ~and() and ~or() syntax for complex conditions
- Updated findEventRSVPs, findUserRSVP, and findUserEvents methods
- Fixed RSVP queries to use proper v2 format for member and event matching

This should resolve the 422 Unprocessable Entity errors that were caused by
using deprecated SQL-like syntax with the v2 API endpoints.
