paul 88919fa0d3 fix: critical boolean compatibility for PostgreSQL/SQLite
Fixed boolean value handling differences between databases:
- SQLite stores booleans as 0/1, PostgreSQL as true/false
- Add formatBoolean() calls to critical queries that were failing

Files fixed:
- adminEvents.js: Fixed status filters and archive queries
- adminDashboard.js: Fixed active/archived event counts
- expirationChecker.js: Fixed expiration checking queries
- dbCompat.js: Updated to avoid circular dependency

Added migration 024 to:
- Enable foreign keys for SQLite (PRAGMA foreign_keys = ON)
- Document boolean compatibility requirements

This fixes queries returning 0 results in SQLite when checking
boolean columns like is_active, is_archived. Critical for
proper event management and expiration handling.

Note: 23 more boolean comparisons remain to be fixed in other files.
