frontend: click a profile row on Home to select it

Mirrors the Profiles screen: the whole non-active row in the Home
'Your profiles' list now selects the profile on click, guarded so the
Copy/Select buttons don't double-trigger. Added a pointer cursor for
non-active rows and a test for row-click selection.
