Profile icons do not have labels on mobile

Hello,

I just came across GraphHopper and I was perplexed by the different bikes profiles. I had a hard time understanding what differed between them and this is not helped by the fact that there is no visible label.

After opening it on my desktop, I realized that the icons make use of the `title` attribute, which is shown when hovering. Unfortunately, you cannot show `title`'s content on mobile, maybe it should be shown when selected (since horizontal space is at a premium)? I made a quick mockup:

No source file or test is named in the issue. Start by locating the profile icon UI and checking how its title attributes behave on mobile; done means the selected profile visibly shows its label without relying on hover, matching the provided mockup.
