Fix how analyses of long notations are displayed on small devices

[stefandesu]

Here's how it looks on my phone:

As you can see, the layout breaks as soon as a caption includes a longer word (because there's not enough horizontal space). I don't think it's possible to fix this for all numbers, but there are some small improvements we could make:

• Reduce left/right margins
• If there's not enough space, only show the ellipsis and hide all other icons in there
• Check if CSS can be adjusted so words break in the middle of the word
• For very long notations, we could also move the caption into the popover and only show the notation part and the ellipsis

This obviously has a very low priority, but it can't hurt to have it as an issue.

On very narrow devices the label should better be hidden or abbreviated. The notation after the label should still be shown, maybe after a colon instead of paranthesis ("Künste: 700", "Museen...: T1--0901-T1--0905:074"...). For large numbers the device must be switched to landscape orientation anyway.
