gsxdsm ad3d26d365 FN-7873: fix mobile floating-window header drag being intersected by page pan-y lockdown ...

Restores reliable single-finger dragging of movable FloatingWindow headers on mobile by reasserting touch-action: none at the mobile breakpoint, and adds regression coverage for the touch drag path.

- Reassert touch-action: none on movable FloatingWindow headers within the mobile media query, excluding full-screen sheet variants (chat, task-detail, workflow-editor, automation, mission-interview, file-browser, pr-create, artifacts-gallery), so the drag-handle contract isn't overridden by the global pan-y lockdown on mobile.
- Add a test verifying the movable mobile drag-handle selector keeps touch-action: none alongside the other opted-out draggable selectors (right-dock-expand-modal header, terminal header).
- Add a test exercising the captured pointermove drag path (pointerdown/move/up with pointer capture) confirming the window repositions correctly on touch input.
- Add a patch changeset for @runfusion/fusion documenting the fix.
