Profiles Phase 2 (drag): make the hybrid-source reorder actually draggable

The hybrid download-source list set item.draggable=true and the help text said
"drag to reorder", but no drag handlers were wired — only the arrow buttons
worked (and _syncHybridOrderFromDOM was dead code). Wired real
dragstart/dragover/drop on each item, reordering _hybridVisualOrder (the same
model moveHybridSource uses) then rebuilding + autosaving. Added grab/grabbing
cursors + a dragging state. The arrow buttons still work unchanged.
