fix: comprehensive PostgreSQL/SQLite compatibility fixes

Critical fixes for database compatibility issues:

INSERT operations:
- Fix all INSERT queries to use .returning('id')
- Handle both PostgreSQL (returns objects) and SQLite (returns IDs)
- Fixed in: events.js, adminArchives.js, adminEvents-enhanced.js, create-test-event.js

Date operations:
- Replace SQLite-specific db.raw("datetime('now', '+30 days')")
- Use JavaScript Date objects for cross-database compatibility
- Fixed in: adminArchives.js

Database utilities:
- Add dbCompat.js utility for handling database differences
- Provides consistent API for inserts, dates, booleans, and DB-specific operations
- Centralized database compatibility logic

Migration:
- Add migration 023 documenting PostgreSQL compatibility requirements
- Ensures future developers are aware of compatibility needs

This resolves all 'not iterable' errors and ensures the application
works correctly with both PostgreSQL (production) and SQLite (development).
