TriggerPatrolForAlert was enqueuing into adHocTrigger regardless of
whether Patrol was enabled. With patrolLoop not running (disabled),
nothing drained the channel — it filled on the 10th alert and spammed
"Patrol trigger queue full, dropping trigger" on every subsequent alert.
Read p.config.Enabled in the same RLock as triggerManager and return
early when disabled.
Fixes#1258
