immediate bug solved

[annrose2277-glitch]

📌 Description

Brief description of what this PR does.

1. Added self.time_left and self.timer_id: To track the countdown and manage the after() loop.
   2. Added self.timer_label: A new UI element to display the remaining time.
   3. Implemented update_timer: Handles the countdown logic and triggers check_result when time runs out.
   4. Updated start_test: To initialize the timer and reset the countdown.
   5. Fixed check_result: Added a timeout parameter. If the test ends via timeout, elapsed_time is set to the exact TEST_DURATION (60s)
   instead of calculating it from time.time(), ensuring consistent WPM results.

so basically when i solved immediate bug solution it automattically solved the time related problems so it closed the remaing issues too.

How to verify the "Ghost Timer" Fix
To see if your fix actually worked (independent of the Git error), run your script and do this:

Click Start Test.

Wait 5 seconds.

Click Restart Test immediately.

Watch the clock: If it counts down normally (59, 58, 57...), the Ghost Timer is solved.

If it jumps (59, 57, 55...), the after_cancel is not triggering correctly.

🛠 Changes Made

-Initialised Timer State: Added self.time_left (set to 60s) and self.timer_id to track the countdown and manage the after() loop.
Added Timer UI: Created self.timer_label to display the remaining time to the user.
Implemented update_timer: This method handles the 1-second interval countdown. When it hits 0, it automatically triggers
check_result(timeout=True).
Reset Logic in start_test: Ensuring any existing timer is cancelled before starting a new one (also fixing the "Ghost Timer"
issue) and resetting the countdown.
The Math Fix in check_result:
* Added a timeout parameter to the function.
* Logical Fix: If the test ends because the timer reached 0 (timeout=True), the code now uses the exact TEST_DURATION (60) for the
elapsed_time variable. This prevents WPM inaccuracies caused by the slight CPU latency (e.g., 60.01s) that occurs when using
time.time().

 if timeout:
         elapsed_time = TEST_DURATION  # Fix: Use fixed duration if timer expires
    else:
          end_time = time.time()
          elapsed_time = end_time - self.start_time
