This commit addresses issues with the question timer in `QuizScreen`.
Key changes:
- **QuizScreenViewModel:**
- Initialize `_remainingTimeSeconds` to `0` instead of `-1` to prevent premature timer display.
- Start timer only if `timerJob` is `null` (not already running) and it's the first question.
- Set `timerJob` to `null` when it's cancelled (on choice selection, moving to next question, or finishing the quiz).
- If a question has no time limit (null or <= 0 seconds), set `_remainingTimeSeconds` to `0` and do not start the `timerJob`.
- When the timer finishes and no choice was selected, set `_selectedChoiceIndex` to `-1` (indicating time ran out) and ensure `timerJob` is nullified.
- **QuizScreen:**
- Conditionally display the `TimerBar` only if `selectedChoiceIndex` is `null` (no choice made yet) AND `timerState.totalTimeSeconds` is greater than `0` (meaning there's a valid timer for the current question). This prevents showing a timer when a question has no time limit.
