Find the better way to show login status so it is visible in main podman desktop window

[dgolovin]

Current version shows login status in three different places:

1. Authentication Settings page
2. Buddy Icon context menu
3. Status bar Hat icon with status as a hint

All above does not allow see login status at glance, there should be a better way to show login status with: color, decorators on the buddy icon or something else should be employed.

Related to #130.

FWIW, using color alone would not be accessible. Personally, I'd prefer if we did something in Podman Desktop that was consistent for all auth providers, so that I have one place to look to see if I'm logged in anywhere.

I find the hat annoying (and if I'm not using RH login atm, the only way to remove it is to delete the extension...), but if we have it why not use 'hat outline' vs 'filled hat'?
