fix(dashboard): use explicit open/close for hover summary slide

The summary sheet was driven by onMouseOver/onMouseOut both wired to
bare onToggle. Those events bubble, so moving between the image, title
and status text (or the sheet sliding in under the cursor) fired
unbalanced toggles - parity flipped and the sheet stuck open or showed
inverted. This predates the v3 migration.

- ContextMenu card Box now owns the hover zone with non-bubbling
  onMouseEnter={onOpen} / onMouseLeave={onClose} from useDisclosure,
  covering the whole card including the rating row instead of just the
  inner link
- Drop the onToggle prop from GameThumbnail and the over/out handlers
  on its Link
- Give the right-click Menu.Content p={4} for breathing room
