🧹 [code health] Avoid 'any' type in autoNotifications filters

[TargetMisser]

🎯 What
Created a new interface FR24Flight to replace the any type used inside array .filter() callbacks for shiftDepartures and shiftArrivals within src/utils/autoNotifications.ts.

💡 Why
Relying on any bypasses TypeScript's type-safety checks, which increases the likelihood of runtime errors. Creating and using FR24Flight provides strong typing for flight scheduling data and aligns with best practices for code health and maintainability.

✅ Verification

• Validated that all properties accessed via optional chaining inside the filter function (e.g., item.flight?.time?.scheduled?.departure) map correctly to the defined FR24Flight type.
• Passed npm run typecheck cleanly.
• Validated no regression via npx jest output.

✨ Result
Improved code safety by providing strict compile-time types for flight data operations.
