Task: Refine the map

At a minimum, the following needs to be done:

1. Make markers non-clickable when selecting route points (route building). Currently, if you click on a marker in this situation, it redirects to the object page.

2. When building routes, update the URL so that routes can be shared and browser navigation works.

3. Add filters for geo-objects (islands, cities, tourist spots, etc.).

4. Expanding the map should not redirect to a separate map page, but should simply render in the document body and be fixed to full screen.
