feat: Show the current users name in the sidebar

[JonathanBout]

Description
This pull request adds a line to the sidebar with the username:

When clicked, you will be sent to the user settings. It also modifies the behavior of the settings button, which now redirects to the global settings and will be hidden when the current user doesn't have the rights for that page.

To make this possible, the backend is modified to also send the username which wasn't sent before.

(resolves #2692)

Oh, I know. It's your first time to Pull a request. It needs maintainer to approve to run the checks.

I don't think addind user and especially logout to the top of the side panel is a good ux practice. There should be a better way to visualize it
