fix(client/apple): the sort menu was brand-purple beside two plain toolbar buttons

A Menu draws its label in the ACCENT colour where a Button draws it in the label
colour, so this one came out tinted next to Add Host and Settings. macOS only: on iOS
every toolbar item is accent-tinted already, and pinning this one to primary would
make it the odd one out there instead of in step.
