revert(repair): remove player movement lock during repair

Drops the useRepairMovementLocked hook, the RepairMovementLockIndicator
overlay, and all PlayerController gating tied to repair sub-states.
The repair flow no longer freezes player movement or shows a lock
banner; the player keeps full control while interacting with the case.
