fix(ui): surface Mirror Options on mobile repo cards and desktop org menu (#365)

The per-repo overrides from #361 were reachable only from the desktop
repositories table. The mobile card layout had no dropdown at all, and
the organizations page had the inverse gap: the item existed in the
mobile card menu but not the desktop one.

Mobile repo cards get a three-dot menu in the header opening the same
MirrorOverridesDialog, plus the Custom badge shown when a repository
overrides something. The organizations desktop dropdown gains the same
Mirror Options item the mobile variant already had.
