fix(admin): refresh sidebar after module toggle on admin page

Activating/deactivating a module from the admin modules page updated only
the page's local state — the sidebar (which refetches its active-module
list on the shared marketplace-store sidebarRefreshKey signal) was never
bumped, so the module's nav link only appeared/disappeared after a manual
full page reload. The marketplace pages already call bumpSidebarRefresh()
after a toggle; mirror that here.
