improve colors, move map labels on top

[karussell]

@Janekdererste mentioned this: the green in the elevation widget does not fit with the "less aggressive" colors elsewhere and we should use

Also the color for the routes should be a bit transparent to

1. allow reading the streetname and
2. knowing the road class.

btw: Qwant + Google Maps draw all labels above the route (because they can assume to always have vector tiles)

Putting the labels on top of the route layer works like this:

The green we use currently is the one taken from graphhopper.com/maps, but I changed it to the one from the 'from' marker now. IMO it now looks a bit dark/brownish though :) c7dca19

Ah, so it turns out this is already fixed and was a caching issue on my side - nice :)

I tried moving the map labels to the top here:

But not really sure yet what to do when the background layer is changed

Also I think our current choice of color for unselected routes is not ideal because it is too similar to the label colors and makes them hard to read

[karussell]

It is not too bad IMO. Sure, the readability of the "L1074" label could probably a bit increased when surrounded with white somehow like it is done for the "Uder" label but you can also just switch the selected route.
