Add Mobile Specific Gesture Support for Better UX

Enhance the mobile user experience by adding swipe gesture support for commonly used actions such as:

Swiping left/right to switch to the next user

Swiping up/down or double-tap to toggle the chat panel

This will make the interface more intuitive and responsive for mobile users, reducing the need for manual button clicks.

Implement touch gesture recognition using a reliable gesture-handling library (e.g., react-swipeable or custom touch event listeners).

Ensure smooth transitions and proper event cleanup.
