🧹 [code health] Avoid 'any' type in parseFlight

[TargetMisser]

🎯 What: Created a comprehensive FR24Flight interface in src/types/flight.ts to replace the any type used across the app (in ShiftTimeline.tsx, FlightScreen.tsx, and fr24api.ts) for mapping FlightRadar24 flight data.
💡 Why: Relying on any bypasses TypeScript's safety features, making it easy to encounter runtime errors with deeply nested data. Centralizing and mapping the nested payload structure explicitly avoids compilation/runtime issues and greatly improves maintainability.
✅ Verification: Verified that npm run typecheck passes with no type errors. Updated FlightScreen.tsx to handle a possibly undefined value correctly. Also verified unit tests continue to pass via npx jest --passWithNoTests.
✨ Result: Reduced any usages significantly. Safer and cleaner flight parsing operations.
