Task/htl 113692 limit dragging to header only

[coolestKev]

Currently, the entire drawer area is drag-to-snappable. Ideally, this action should only be triggered by dragging the header handle, not other parts of the drawer content.

Previously, this introduced a bug where content scrolling triggered the drag-to-snap behavior, which was then patched with a workaround in #1542 by differentiating touch actions.

However, that approach doesn't work well on real devices, introducing jankiness in the scroll action. Therefore, we're revisiting this with a new approach - using the useDragControls hook from framer-motion to limit where we can drag (in this case, the header). This way, we're properly compartmentalizing the interactive areas.
