feat(ui): Add the repository description to taskbar

[lupusA]

Hi,

this PR adds the repository description to the taskbar while starting up or initializing kopia. It was mentioned that, if there is no connection to the repository, multiple "initializing" or "not connected" repository show up. It is not easy to distinguish between multiple repositories in this case.

• While calling newServerForRepo, the corresponding config is read to extract the description
• The description is then added to the taskbar
• The read operation for the repository config is async, not blocking the creation of the server
• Removed deprecated call of file.resolvePath

Feedback is welcomed. This PR partly refers to #3418.
