c90a15e9 - Show sidebar conversation scrollbar only on hover for mouse devices

Show sidebar conversation scrollbar only on hover for mouse devices Adds a scrollbar-on-hover utility that keeps the scrollbar gutter but makes the thumb and track transparent until the container is hovered. Gated behind @media (hover: hover) and (pointer: fine) so touch devices keep the always-visible behavior. Applied to the NavMenu conversation list.
