* admin/maintenance: reload in-flight tasks on startup instead of discarding

LoadTasksFromPersistence deleted all persisted task files on startup and
relied on the scanner to re-detect, so saved task state was never consumed
— the persistence was effectively write-only. Reload non-terminal tasks
(pending/assigned/in_progress) into the queue, resetting in-flight ones to
pending since their worker is gone after a restart (maintenance tasks are
idempotent). Terminal task files are dropped; the scanner still backfills
anything not persisted.

* address review: nil-guard reloaded tasks and SyncTask to ActiveTopology

- skip nil entries from LoadAllTaskStates (corrupted state)
- re-sync restored tasks with MaintenanceIntegration so ActiveTopology
  (in-memory, empty on startup) knows about them; otherwise GetNextTask's
  AssignTask rejects them as unknown and they never get assigned
