FN-7478: add local server desktop switch option

Restore the desktop connection manager's local server destination alongside saved remotes.

- Add a Local Server card for desktop-shell switching with active state handling.
- Switch remote profile selection into remote mode before activating the profile.
- Cover desktop local/remote switching behavior with tests and localized labels.
- Document the switch-server local option and add the published package changeset.
