- PauseController now uses redis.asyncio for cross-worker state - Pause survives worker restarts (Redis key protocol:paused) - Fail-closed: defaults to paused on Redis outage for safety - 5s in-memory cache to avoid Redis round-trip on every request - verify_admin_token uses hmac.compare_digest for constant-time comparison - Router endpoints use APIError envelope - 23 tests covering Redis state, cache, fail-closed, exempt paths Closes Quantarq#416

Description
Replace the in-process PauseController with a Redis-backed implementation that propagates pause state to all workers and survives restarts. Fix admin token comparison to use constant-time hmac.compare_digest.
