This updates some minor issues that would cause warnings or make things appear to not work, even though they would work fine when actually running a backup.
This PR has a large blast radius because it takes the final step and bumps up the Controller to be fully async.
We have historically done a piece-by-piece update, so all operations were already async but the controller interface was kept synchronous.
With this update, the controller is now fully async and all tests are updated.
Most places where the new C# compiler warns about function names not ending in `Async` were also adressed, giving a massive refactor change.
Functionally, no changes are done.
Added auth requirement on all endpoints.
Added SignIn-, Access- and Refresh-Tokens based on JWT.
Upgraded stored password to be based on PBKDF2.
Added default password assignment.
Updated logic to support auth-header and re-sign-in for tray-icon and web-ui.
Re-implemented everything using ASP.NET.
Changed some requests to use JSON instead of FORM data.
Some work towards deleting the FIXMEGlobal instance.
Auth is missing, XSRF does not work correctly.
