- REST API: Fix id type from integer to UUID, add device/equipment fields, correct rate limiting info (100 req/min, not "none"), add 429 status code - Mobile API: Fix search_callsign response field (lon not lng), add path to packet fields, correct rate limiting/timeout docs, clarify update_bounds behavior - Fix flaky pipeline tests (async race on global Application config)
