* admin: fix capacity leak in maintenance system by preserving Task IDs
Preserve the original TaskID generated during detection and sync task
states (Assign/Complete/Retry) with ActiveTopology. This ensures that
capacity reserved during task assignment is properly released when a
task completes or fails, preventing 'need 9, have 0' capacity exhaustion.

* test: rename ActiveTopologySync to TaskIDPreservation
Rename the test case to more accurately reflect its scope, as suggested
by the code review bot.
* Add TestMaintenanceQueue_ActiveTopologySync to verify task state synchronization and capacity management
* Implement task assignment rollback and add verification test
* Enhance ActiveTopology.CompleteTask to support pending tasks
* Populate storage impact in MaintenanceIntegration.SyncTask
* Release capacity in RemoveStaleWorkers when worker becomes unavailable
* Release capacity in MaintenanceManager.CancelTask when pending task is cancelled
* Sync reloaded tasks with ActiveTopology in LoadTasksFromPersistence
* Add verification tests for consistent capacity management lifecycle
* Add TestMaintenanceQueue_RetryCapacitySync to verify capacity tracking during retries
