for each language option for each instance.

Aria did not match label when changing langauge, and an id was

Instead of forcing a reload of the page, we trigger a new api call in
the background, meaning we don't get a flash when verifying an identity.

The profile page of a guest now shows a verification button if the guest
has a passport or national identificaiton number that has not been
verified. Clicking the button shows a dialog, with a confirmation button
which triggers a PATCH request to the backend and reloads the page when
it returns.
