Make selected Pin better visual on the map

[wellemut]

Problem

On this view you just dont know, which Pin is the selected one https://www.kartevonmorgen.org/m/main/e/3891326f877342f39d0fa5c0c8dc3c36?c=48.7786%2C9.1778&z=14.00

Solution

• Make unselected Pin partially transparent (like in old version https://v0.kartevonmorgen.org/#/?entry=13eb2b40d1434e4796581cdb9a15ca20&center=48.834,9.192&zoom=12.00&dropdowns=kvm)
• Make selected Pin red - @laura should define a new color
• Make the selected Pin come upfront not needed
• Make selected Pin bigger would cause too much action on the map

If you browse the search results on the left, the changing of background entries works, but not if you brows the map directly. Than the focus stays on the first selected pin.
