Add basic auth

[joundso]

Is your feature request related to a problem? Please describe. A secured ollama installation with basic auth can't be used since there is no settings field for the username and password.

Describe the solution you'd like Settings field for username and password - or even better a window asking for credentials storing them besides the (potential synced) settings.

Describe alternatives you've considered None.

Additional context None.

Thanks in advance!
