Quality-gate fixes (new-code conditions on PR #902):
- new_security_hotspots_reviewed: drop the fake "http://nextcloud" host in the
manager tests to https:// (python:S5332 ×2).
- new_security_rating: generate the integration test's fake app password with
secrets.token_urlsafe instead of a hardcoded literal (python:S2068).
- new_reliability_rating: restructure the user_manager sleep so an explicit
await checkpoint lives inside the cancellation scope — await one waiter
directly while watching shutdown via start_soon (python:S7490). Behaviour is
unchanged: timeout, shutdown, or a provisioning ring all end the sleep.
Review nits:
- Move the shutdown test's fail_after(2) to wrap the whole task group so it
actually bounds the task-group exit (was guarding a no-op sleep); drop the
sleep(0) stub (python:S7491).
- Type _wake_on's wait_fn as Callable[[], Awaitable[object]].
- Note in _wire_vector_sync_state why provision_signal is set on the singleton
only, not fanned out to app.state.
