Add per-row remove button to trusted clients list (#184)

Removing a single trusted client required a right-click context menu
or select-then-Delete, neither of which is discoverable, while bulk
removal already had a visible "Remove All" button. Add a visible
per-row remove button alongside the existing context menu.
