Timer continues after quiz ends

[VikasKSingh05]

Description:

When the quiz ends, the timer does not stop. It keeps reducing and eventually goes into negative values. This also incorrectly affects the total time spent in the quiz, as the counter keeps increasing even after completion.

Steps to Reproduce:

• Start a quiz.
• Let the timer run until the quiz ends (either by finishing questions or time running out).
• Observe that the timer still continues to decrement into negative values.
• Check the "total time spent" – it keeps increasing even after the quiz has ended.

Expected Behavior:

• When the quiz ends, the timer should immediately stop.
• The total time spent should freeze at the actual completion time.

Actual Behavior:

• Timer keeps running into negatives.
• Total time spent keeps increasing incorrectly.
