Subject: [PATCH] feat: add zone name labels and hover coordinates to world map

- Draw zone name text centered in each zone rect on the continent view;
  only rendered when the rect is large enough to fit the label without
  crowding (explored zones get gold text, unexplored get dim grey)
- Show WoW coordinates under the cursor when hovering the map image in
  continent or zone view, bottom-right corner of the map panel
