feat(acars): add message translator and ADS-B datalink integration
Add ACARS label translation, message classification, and field parsers so decoded messages show human-readable descriptions instead of raw label codes (H1, DF, _d, 5Z, etc.). Integrate translated ACARS messages into the ADS-B aircraft detail panel and add a live message feed to the standalone ACARS mode. - New utils/acars_translator.py with ~50 label codes, type classifier, and parsers for position reports, engine data, weather, and OOOI - Enrich messages at ingest in routes/acars.py with translation fields - Backfill translation in /adsb/aircraft/<icao>/messages endpoint - ADS-B dashboard: DATALINK MESSAGES section in aircraft detail panel with auto-refresh, color-coded type badges, and parsed field display - Standalone ACARS mode: scrollable live message feed (max 30 cards) - Fix default N. America ACARS frequencies to 131.550/130.025/129.125 - Unit tests covering all translator functions Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
