fix: Align NestJS entity columns with service expectations
Resolved 12 TypeScript compilation errors caused by mismatched column names between TypeORM entities and service layer.
Entity changes:
- NotificationsConfig: Renamed email_alerts_enabled → email_enabled, added email_address, standardized notification event column names (notify_on_start, notify_on_stop, notify_on_crash, etc.)
- ScheduledTask: Renamed is_active → is_enabled, added last_run timestamp
- TeamMember: Renamed accepted_at → joined_at to match service expectations
- Role: Added description column for custom role metadata
Service changes:
- JwtStrategy: Updated to reference joined_at instead of accepted_at
All services now compile cleanly against updated entity schemas.
