Enhance map styling and dark mode support

- Implemented dynamic tile layer selection based on the current theme (light/dark), improving visual consistency with the overall design.
- Updated attribution handling for the tile layer to reflect the theme, ensuring proper credit is given based on the selected tiles.
- Added custom styles for Leaflet controls to align with the shadcn/tailwind theme, enhancing the user interface and experience.
