feat: Implement flight search functionality

This commit introduces the ability to search for flights based on user-defined criteria.

Key changes:
- Added `GetFlightsSearchContentUseCase` interface in the domain layer and its implementation `GetFlightsSearchContentUseCaseImpl` in the repository layer to handle flight search logic.
- Implemented `FlightDomainMapper` to map `FlightResponse` from the API to the domain `Flight` model.
- Updated `NetworkModule`:
    - Introduced `ServicesAPI` and `NativeAppsAPI` qualifiers to differentiate between Retrofit instances for different Ryanair APIs.
    - Configured a new Retrofit instance for the `nativeapps.ryanair.com` base URL.
    - Modified `FlightService` to use the `nativeapps.ryanair.com` base URL.
- Updated `FlightService` endpoint to `api/v4/en-gb/Availability`.
- Integrated `GetFlightsSearchContentUseCase` into `HomeScreenViewModel` to trigger flight searches.
- Created `SearchOptions` data class in the domain layer to encapsulate search parameters.
- Added `GetFlightsSearchContentUseCaseModule` to provide the use case implementation via Hilt.
