Name the reporting provider in Contacts and Cockpit counts

The Cockpit Contact counts named fixed providers (OpenSky, adsb.lol,
AISStream) while the Layers panel and Contacts named the provider the last
snapshot reported, and the vessels layer kept that name out of getStats(),
so Contacts always said AISStream. Each cohort now carries the provider and
whether it answered as a fallback or from a stale snapshot, and both views
show it the way the Layers row does ("adsb.lol · FALLBACK").

Fixes HAL-721.
