Fix MPV menu: resolve Lua syntax error and enhance logging

- Remove extra 'end)' that caused '<eof>' expected syntax error at line 2834
- Add comprehensive logging to M.show_menu() with [MENU] prefix
- Add logging wrappers to keybindings (m and mbtn_right)
- Implement fallback menu opening methods (commandv and command)
- Fix audio-display mpv.conf setting to 'no' (was invalid 'yes')
