fix: remove obsolete map share toggle and make public desktop entries openable

Map permission is always enabled on new links (share always includes map).
Removed the toggle from the share settings UI since the map is now always
part of the combined timeline+map view with no standalone value in toggling it.

Desktop entry cards on the public share page now open MobileEntryView on click,
matching the mobile behaviour added in #826.
