Compass UI with real-time directional updates

[Yugesh-Kumar-S]

Description:

This issue aims to implement the Compass UI in the PSLab Flutter app by porting the corresponding feature from the PSLab Android app. The compass should display real-time directional changes using device sensors.

Objectives:

• Maintain consistency with the existing PSLab Android app’s Compass behavior.
• Ensure smooth transition and rotation of the compass needle based on device orientation.
• Integrate real-time directional updates using magnetometer and accelerometer sensors.
