Refactor: Migrate to kotlinx-datetime and implement flight search results display

This commit migrates date handling from `java.time` to `kotlinx-datetime` across various modules. It also introduces the display of flight search results on the home screen.

Key changes:
- Replaced `java.time.LocalDate` and related classes with `kotlinx.datetime.LocalDate` in:
    - `ui/home/src/main/kotlin/dev/adriankuta/flights/ui/home/components/DatePicker.kt`
    - `model/repository/src/main/kotlin/dev/adriankuta/flights/model/repository/usecases/GetFlightsSearchContentUseCaseImpl.kt`
    - `ui/home/src/main/kotlin/dev/adriankuta/flights/ui/home/HomeScreen.kt`
    - `ui/home/src/main/kotlin/dev/adriankuta/flights/ui/home/HomeScreenViewModel.kt`
    - `domain/types/src/main/kotlin/dev/adriankuta/flights/domain/types/TripDate.kt`
    - `ui/home/src/main/kotlin/dev/adriankuta/flights/ui/home/components/PassengersOptions.kt`
    - `ui/home/src/main/kotlin/dev/adriankuta/flights/ui/home/components/SearchForm.kt`
    - `domain/search/src/main/kotlin/dev/adriankuta/flights/domain/search/entities/SearchOptions.kt`
- Added `kotlinx-datetime` dependency to `build-logic/convention/src/main/kotlin/dev/adriankuta/partymania/ConfigureKotlinAndroid.kt`.
- Implemented `SearchResults.kt` composable to display flight search results.
- Updated `HomeScreen.kt` to show `SearchResults` when results are available and handle back navigation.
- Modified `HomeScreenViewModel.kt`:
    - Introduced `SearchResultUiState` to manage search result states (Loading, Success, Error, Idle).
    - Updated `search()` function to fetch and expose flight results.
    - Adjusted initial airport list in `homeUiState` to filter for "DUB" and "STN" and ensure destination isn't the same as origin.
- Updated `FlightDomainMapper.kt` to parse date strings into `kotlinx.datetime.LocalDate`.
- Added `HomeUiStatePreviewParameterProvider.kt` and `FlightPreviewParameterProvider.kt` for Compose previews.
- Removed Timber dependency from `ui/home`, `domain/search`, and `domain/types` modules as it's now provided via convention plugin.
