v0.65.0: per-airport job pools with real-time refresh — open jobs spawn per pool airport (grounded/flying/queued locations) in a fixed POOL_BANDS composition, expire on the wall clock after JOB_LIFETIME_MS even while the world is frozen, and refill taken slots after a per-band cooldown; /api/state + SSE filter open jobs to pool origins and expose expiresRealMs for the right-pane countdown
