CommandPalette: replace workspaceProjects with getCurrentUserProjects
(no workspace dependency so it works outside WorkspaceProvider).
Repos fetched per-project to preserve correct /repository/ns/repo
routes. Keyboard shortcut correctly matches Ctrl+Alt+F / Cmd+Ctrl+F.
sidebar-user: fix notification button layout — bell icon and label
now on the same row instead of separate stacked elements.
