feat(contacts): deselect on empty click, actions left of globe, right-click menu

Three interaction refinements to the address list:
- The globe badge now stays pinned far-right; the per-row copy/edit/delete actions
  appear to its LEFT on hover/selection instead of replacing it.
- A left-click on empty space in the Cards/List area clears the current selection
  (no row/action hovered -> deselect).
- Right-clicking a row (any view) selects it and opens a shared context menu
  (Copy address / Edit / Delete), rendered once after the list.

Build + hygiene clean.
