Changelist

This PR implements the Sprint 3 Alarm Clock app.

The application starts with the heading showing Time Remaining: 00:00 and no alarm sound playing.

When the user enters a number of seconds and clicks the "Set Alarm" button, the heading updates immediately in mm:ss format. The countdown then decreases by one second every 1000 ms.

When the timer reaches 00:00, the background colour changes and the alarm sound starts playing continuously. Clicking the "Stop Alarm" button stops the alarm sound.

I also added logic to clear any existing timer before starting a new one, reset the background state when a new alarm is set, and format the display consistently.

The app was tested in the browser to confirm:

• the initial heading shows 00:00
• the timer formats values correctly
• the timer counts down every second
• the background colour changes when the timer reaches zero
• the alarm sound plays at zero
• the stop button stops the alarm sound

I also ran the provided tests for the alarm clock task, and all tests passed successfully.
