Airport popup Relocate works for flying/repairing planes via queue (ISS-096, v0.49.0)

The airport popup's Relocate row now lists ALL planes instead of only
grounded ones; the click handler picks the endpoint by the selected
plane's current status — available → /fly (unchanged), flying/repairing
→ /queue so the destination is appended to the flight queue and chains
on landing. No-planes fallback reworded to 'No planes to relocate.'

E2E +1: relocation.spec.ts dispatches the starter on a leg via API,
slows the sim to 1x, opens the popup for a different airport, selects
the flying plane and clicks Relocate here — asserts the queue contains
the clicked ICAO while the plane still flies its original destination.
