Live feed: FR24 primary, OpenSky fallback

OpenSky's free anonymous tier has sparse ground coverage — at DAL it
returned a single airborne aircraft when there were 3+ SWA jets
visibly parked on the apron. FR24's feed.js aggregates ASDE-X, MLAT,
and multiple community ADS-B feeds and reliably surfaces ground
aircraft at major airports. We now query FR24 first and fall back to
OpenSky only when FR24 errors.

FR24's payload also carries departure + arrival IATA + flight number
+ aircraft type + tail number inline, so we shortcut the
route-explorer schedule lookup in the detail sheet: a new
`LiveAircraft.Enrichment` struct holds those fields, and the
ResolvedRoute cascade gains a `.fromFR24` first-tier case that uses
them directly. The `typeCode` and `airlineICAO` computed properties
prefer enrichment values over the AircraftDatabase / callsign-prefix
heuristics — this also fixes the case where FR24 callsigns use the
IATA carrier ("AA0013") which our 3-letter-prefix derivation would
have rejected.

OpenSky still owns trail polylines and recent-flights history; only
the live position fetch swapped sources.
