Refactor: Clean up QuizScreen and adjust image scaling

This commit includes several refactoring changes and a minor UI adjustment:

- **UI Layer (`ui:quiz` module):**
    - In `QuizScreen.kt`:
        - Removed the unused `timer` extension function for `LazyListScope`.
        - Applied `@Suppress("LongMethod")` to `QuizScreenSuccess` composable.
        - Simplified the `modifier` usage within the `Box` in `QuizScreenSuccess`.
    - In `components/QuestionContent.kt`:
        - Changed `ContentScale` for `AsyncImage` from `FillWidth` to `Fit`.
        - Aligned the `AsyncImage` to `Alignment.CenterHorizontally`.
- **Data Layer (`data` module):**
    - In `QuizRepositoryImpl.kt`:
        - Reordered import statements.

Note: The commit also includes changes to a binary file `App.apk`, which are not detailed here.
