feat: Add Retrofit and Moshi for network operations

This commit introduces Retrofit and Moshi to handle network requests and JSON parsing.

Key changes include:
- Added Retrofit, Moshi, OkHttp, and OkHttp Logging Interceptor dependencies to `libs.versions.toml` and `model/data/api/build.gradle.kts`.
- Created data classes for API responses: `AirportResponse`, `RouteResponse`, and `FlightResponse`.
- Defined Retrofit service interfaces: `AirportService`, `RoutesService`, and `FlightService`.
- Implemented a Hilt `NetworkModule` to provide Retrofit, Moshi, and OkHttpClient instances.
- Added a Detekt configuration file for the `model/data/api` module.
- Temporarily commented out `configureFlavors` in `AndroidApplicationConvention.kt` and `ConfigureLibrary.kt`.
