Improve "region picker": searchability
Description
We get questions about how to reach 'Germany', because 'Europe' is not pre-chosen.
It would be great to make the regions also searchable.
Impact
Every FS picking their region / joining a region.
Proposal
(wait for #874 (closed) to be solved: Providing the search from the server might be a thing of little effort, but the front-end does not support it currently)
Create a new endpoint in the SearchRestController
Create a new function in a gateway (Alex couldn't find a suitable one right now).
Set Europe as default.
Type "Luck" to find Luckenwalde, type 14943 to find Luckenwalde, have the manual dropdown as a manual alternative. (How do you propose to solve the problem?)
