APIv2 doesn't follow redirects, e.g. for HTTPS

[CrsiX]

When using non-HTTPS server URL for HTTPS-only servers, the redirect is not followed, leading to an unusable API experience. The user should either be notified, or the redirects should be followed automatically.

Example log:
2023-05-14T11:53:48.034006Z [threadpool-daemon-1] [ApiV2Wrapper] 'POST http://runciv.hopfenspace.org/api/v2/auth/#': 301 Moved Permanently (42 ms)

[CrsiX]

The detection of the API works smoothly. I suspect that POST requests are not repeated to the new destination (= not following the 301), but they are required for login and other actions.
