Add service to clean expired locks and related tests

- Introduced `CleanOldLock` service to remove expired locks older than 24 hours.
- Added `removeExpiredBefore` method in `StoredObjectLockRepository` for efficient deletion of expired locks.
- Created `CleanOldLockTest` to verify the cleaning service functionality using `MockClock`.
