feat(login-guard): unlock entire scope and report deleted keys

Admin login-lock reset now SCANs and clears all auth:login:* keys (any
scope) and surfaces redis_deleted_keys / fallback_deleted_keys back to
ops-web so the operator can tell whether the cache was actually hit.
Also tracks paired keys via a per-identifier index plus an unlock marker
so legacy/in-flight pair locks get cleared on the next acquire.
