- 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).

Background vector sync discovered newly provisioned users only on the
periodic user-manager poll (VECTOR_SYNC_USER_POLL_INTERVAL, default 60s),
delaying first indexing by up to a minute. Add a ProvisionSignal doorbell
that provisioning paths ring after storing a user's app password, waking
user_manager_task to re-poll and spawn the user's scanner at once. The
periodic poll remains the backstop (covers cross-replica provisioning).
- ProvisionSignal (stable reference, wait-and-re-arm) held on
VectorSyncState; closes the lost-wakeup window (no await between observing
the ring and re-arming; anyio.Event stickiness covers a mid-poll ring)
- user_manager_task races its poll timeout against the doorbell + shutdown
- notify_user_provisioned() rung from the three app-password provisioning
sites: Login Flow v2 web, MCP provisioning tool, management/BasicAuth API
Note: the pre-existing scanner_wake_event was never .set() and only wakes
existing scanners; a brand-new user has none, so the manager is what must
be nudged.
