Eliminate Valkey queue polling fallback (phase 2 CPU optimization)

Browse Source 
Replace hardcoded 1-5s polling constants with configurable
QueueWaitTimeoutSeconds (default 0 = pure event-driven). Consumers
now only wake on pub/sub notifications, eliminating ~118 idle
XREADGROUP polls per second across 59 services. Override with
VALKEY_QUEUE_WAIT_TIMEOUT env var if a safety-net poll is needed.
