mobile/dive-edit: fix broken editable combo boxes

This is a partial revert of commit 99438121c4 ("mobile/dive-edit: use template
components and theme colors")

Clearly the information given in the Qt documentation on how to theme ComboBox
is flat out broken. The trade-off between 'better dark theme' and 'broken user
experience' is fairly easy to make.
