Move drag handle to top center edge of widget card

- Move drag handle out of widgetHeader into widgetCard directly so it
  sits at the top edge of the card, centered horizontally
- Style as a small tab (36x14px bar) protruding from the top border
- Always visible in edit mode for all widget types
- Remove old inline-flex overrides that conflicted with the new layout
