Visual Redesign to improve UX

[nichtich]

The current version is not designed for usability at all.

Some things that I already noticed:

• There needs to be a loading indicator when something from an API is loaded. This should also prevent the user from clicking another option during that time, or we need a way to cancel requests if the user clicks something else while it is still loading. (I'm pretty sure you could cause bugs by clicking too rapidly at the moment.)
• The arrows and icons are unclear, some aren't even visible on macOS.
• Many elements are clickable, but it's not clear what will happen if you click them. For example, you can't click on a database's name to select it, you have to click on the radio icon (usually, you can click either the icon or the label).
• The examples are clickable, but they don't look like they are. (Also, do they need to occupy their own row the whole time? They are useful for testing and demonstration, but not for actual usage of coli-rich.)
• Enrichments shouldn't be editable (or should they?)
• Everything could look much nicer of course.
• Do we need multi-language support?

Do we need multi-language support?

No, the web interface is German because all users are German librarians
