Three independent issues conspired to make stress tests record 0 requests:
1. Every virtual user did /auth/login in on_start. With 1000 users in a
spike window, bcrypt-bound logins never finished and on_start failed
for all users — aggregated requests stayed at 0. Pre-fetch a single
admin token in the fixture (cached per-host) and pass it via
DECNET_STRESS_TOKEN so locust users skip the login storm.
2. Locust exits non-zero on any request failure by default, causing
run_locust to throw away an otherwise valid stats CSV. Pass
--exit-code-on-error 0 so per-test assertions are the only fail gate.
3. test_stress_sustained ran two locust subprocesses against the same
uvicorn. Phase 1's keep-alive connections wedged phase 2 into 0
recorded requests ~2/3 of the time. Refactored stress_server into a
start_stress_server() context manager and gave each phase its own
uvicorn.
Stable 3/3 on full suite, 3/3 on test_stress_sustained alone.

verify_password / get_password_hash are CPU-bound and take ~250ms each
at rounds=12. Called directly from async endpoints, they stall every
other coroutine for that window — the single biggest single-worker
bottleneck on the login path.
Adds averify_password / ahash_password that wrap the sync versions in
asyncio.to_thread. Sync versions stay put because _ensure_admin_user and
tests still use them.
5 call sites updated: login, change-password, create-user, reset-password.
tests/test_auth_async.py asserts parallel averify runs concurrently (~1x
of a single verify, not 2x).
