fix(kanban): wake the origin on review handoffs and triage escalations

`review_requested` and `block_loop_detected` are terminal event kinds that
hand a decision back to the origin subscriber, but neither was listed in the
gateway notifier's `_WAKE_KINDS`. A `notify+wake` subscription therefore got
the passive ping only and the origin agent never took a turn — so an agent
that delegated implementation work slept through the "ready for review"
handoff and through a task being routed to triage, while the equivalent
`blocked` event woke it.

Add both kinds to the wake set, add their status strings to the synthetic
wake message in every locale, and document which events wake.
