Adds touch-screen support for resizing filmstrip and chat panels to enable tablet and touch-laptop users to adjust panel widths. Previously, drag handles only worked with mouse hover, making panels non-resizable on touch devices. Changes: - Implement Pointer Events API for unified mouse/touch handling - Add touch device detection with screen size threshold - Make drag handles always visible on touch devices with padding for easier tapping - Maintain identical visual layout between touch and non-touch versions Touch devices with sufficiently large screens now have fully functional drag handles with appropriate hit targets while smaller devices remain disabled to preserve mobile UX.
