- ProvisionSignal.wait() re-arms in a finally so a cancelled wait (shutdown
racing the doorbell) leaves a fresh unset event, not a stale set-but-consumed
one; preserves the no-await-before-swap lost-wakeup guarantee.
- Hoist user_manager_task's _wake_on helper out of the while loop (one object,
not one per iteration).
- Test: assert ProvisionSignal via its public wait() contract instead of the
private _event attribute.
- Add test_provision_app_password_wakes_user_manager covering the
api/passwords.py wake path (previously only LFv2 web + MCP tool were tested).
