feat(frontend): add blank Global Settings page (#2218)

* feat(frontend): add blank Global Settings page

Add a Global Settings page to the desktop renderer, reachable from the
sidebar Settings menu when no project is selected. The project-scoped
Settings entry stays when a project is active; otherwise the menu shows
Global settings, which opens the new /settings route. The page body is
intentionally empty for now and will be filled in incrementally.
