Move feedback button to overflow menu

To be consistent with normal view and avoid nested dialogs.

Also disable space for the PTT key when the feedback dialog is visible,
since otherwise you can't type a space. Involves some rearrangement of
modal state.

Remove accidentally comitted vite port config.
