Fix error reporting in admin and some small fixes

- Fixed a bug in JavaScript which caused no messages to be shown to the
user in-case of an error send by the server.
- Changed mail error handling for better error messages
- Changed user/org actions from a to buttons, this should prevent
strange issues in-case of javascript issues and the page does re-load.
- Added Alpine and Debian info for the running docker image

During the mail error testing i encountered a bug which caused lettre to
panic. This panic only happens on debug builds and not release builds,
so no need to update anything on that part. This bug is also already
fixed. See https://github.com/lettre/lettre/issues/678 and https://github.com/lettre/lettre/pull/679

Resolves #2021
Could also fix the issue reported here #2022, or at least no hash `#` in
the url.
