feat: Introduce Network Functionality and Screen Time Implementation

- Implement `NetworkModule` for HTTP client management with JSON serialization.
- Add `kotlinx-serialization-json` and `ktor-client` dependencies.
- Update `Greeting` class to perform network requests to fetch and display time data.
- Add `NetworkResponse` and `TimeResponse` data classes for handling the remote API response.
- Introduce `ScreenTime` interface for platform-specific screen time data.
- Implement `ScreenTime` for Linux and Android, with basic or placeholder logic.
- Add `INTERNET` and `ACCESS_NETWORK_STATE` permissions to Android's `AndroidManifest.xml`.
- Add `ScreenTime.native.kt`, `ScreenTime.jvm.kt` and `ScreenTime.android.kt` to separate platform-specific code.
- Implement `kotlin("plugin.serialization")` plugin in shared module.
- Update dependencies.
- Add `ignoreUnknownKeys` and `coerceInputValues` for JSON serialization.
- Update `App` to display time data from remote API.
