Integration with GNOME Online Accounts (when using Nextcloud)

[ekasprzak]

Is your feature request related to a problem? Please describe.
Current login solution requires typing all the fields (user, pass, url) manually, having MFA enabled, it also requires manually creating a specific password in NC for every new app.

Describe the solution you'd like
Planify takes all above data from Gnome Online Accounts (if NC integration is enabled there of course).

Additional context
It's implemented in Gnome ToDo/Endeavour and was recently added in Errands app (in v. 45.1.6)
If you consider implementing that - maybe this would be a good start as an inspiration.

Gnome 46 added a new WebDAV provider to Gnome Online Accounts: https://release.gnome.org/46/#upgraded-online-accounts-now-with-onedrive

It would be nice if planify could pick those up automatically (and sync tasks from non-Nextcloud accounts too).
