Finish Map Component

## Task Description
Enhance the Map component by adding chest locations and island visualization features to improve its functionality and usability.

## Subtasks
- [ ] Add chest locations to the map, including treasure chest types (e.g., rupee chests, heart pieces, charts).
- [ ] Implement a checklist for marking chests as collected.
- [ ] Add island visualization overlays to highlight explored/unexplored islands.
- [ ] Include toggles for showing/hiding chest locations and other collectibles.
- [ ] Ensure the map integrates seamlessly with the existing zoom and detail levels.

## Notes
- Chest locations should be categorized (e.g., treasure charts, dungeon chests, overworld chests).
- Island visualization should use a color-coded system to indicate exploration status.
- The design should match WWHD as much as possible for greater transfer of knowledge.
