Refactor: Clean up imports and formatting in UI components

This commit addresses minor code style issues by removing unused imports and standardizing formatting across several UI components within the `ui:quiz` module.

Key changes:

- **`ui/quiz/QuizScreen.kt`**:
    - Added `modifier` parameter to `QuizScreenLoading`'s `CircularProgressIndicator`.
- **`ui/quiz/QuizScreenViewModel.kt`**:
    - Improved code formatting for readability, particularly around `timerState` updates and retrieving question times.
- **`ui/quiz/components/TimerBar.kt`**:
    - Removed unused import `androidx.compose.ui.draw.clipToBounds`.
- **`ui/quiz/components/QuestionContent.kt`**:
    - Reordered imports alphabetically.
- **`ui/quiz/components/Choices.kt`**:
    - Removed unused import `androidx.compose.foundation.layout.width`.
- **`ui/quiz/components/Toolbar.kt`**:
    - Removed unused imports `androidx.compose.foundation.layout.fillMaxWidth` and `androidx.compose.foundation.layout.height`.
