- Introduced session management endpoints to list, revoke, and cleanup sessions per user. - Added cron-based job for periodic cleanup of expired sessions. - Implemented `CRUDSession` for session-specific database operations. - Integrated session cleanup startup and shutdown events in the application lifecycle. - Enhanced CORS configuration to include `X-Device-Id` for session tracking. - Added comprehensive integration tests for multi-device login, per-device logout, session listing, and cleanup logic.
