Feature: Add a button to mute/unmute all game audio

It would be helpful to add a button in the game UI that allows players to turn off (mute) or turn on (unmute) all game audio, including sound effects and background music.

The button should be easily accessible during gameplay.
When muted, no sound effects or music should play.
The button should visually indicate whether audio is currently on or off.
This feature would improve accessibility and user experience for players who prefer to play without sound
