fix focus border not appearing on workspace and output panels

[DokaDev]

spotted a regression from the OnFocus and OnBlur centralisation work. workspace and output panels weren't showign green borders when focused, while migrations and details worked fine

turned out to be a reference issue. ApplyFocusStyle() was accessing the view through self.view(the BaseContext field), but gocui's SetView() can return a different reference each frame. migrations and details never had this problem because they set colours directly on the local v variable in Draw(), never going through self.view

fix is simple. replaced the ApplyFocusStyle() call with inline colour setting in Draw(), same pattern migrations and details already use. all four panels are consistent now

also I bumped versino to v0.3.2
