wiring the poller into both boot paths (V-637)

It reaches the daemon through ipc.CoreAPI and nothing else, so a telegram
turn takes the path POST /api/chat already takes: Chat returns the reply and
the trace id it collected off the context (V-630), and CorrectTurn writes
the label. Nothing in internal/delivery learns what a handler is.

Wired on the unlocked start and on the passkey unlock, like the mail intake,
so telegram behaves the same either way. A sink that will not build is
logged rather than fatal here, because wireDispatcher already failed the
boot on the same config.
