fix: wire adapter name mismatch in satpass event path

Central publishes sat events with wire adapter names celestrak_tle,
n2yo_visualpasses, and satpass_predict.  Task C's routing matched on
sat_tles/sat_tle/sat_passes — names that exist nowhere on the wire —
so every sat event was silently dropped at three kill points:

1. CENTRAL_ADAPTER_TO_SOURCE map (consumer.py line ~216)
2. _normalize dispatch conditionals (consumer.py line ~549)
3. satpass_handler adapter guard (satpass_handler.py line ~118)

All three now use the correct wire names.  Both handlers also gain an
enabled gate that returns None when satpass.enabled=false, logging at
INFO once per process lifetime via a _disabled_logged function flag.

Existing test fixtures updated for the new adapter names and the
enabled gate (cfg.enabled=True in mock, _disabled_logged cleanup).
