Fix menu input: name the VSMX script 'main' so button events resolve

Button events in the RCO are named 'script:/main/mm_on_focus_up' etc., but
the interpreter was constructed with name 'menu', so interpretScript built a
'script:/menu/' prefix that never matched and button navigation/selection
silently did nothing. Also route key presses through a scene event filter so
arrow keys reach the handler before JavaFX focus traversal.
