Fix font rendering, layout, and Windows tray restore

- Put CJK font at END of family list (push instead of insert(0)) so
  egui's built-in Latin fonts render ASCII/Latin text first, with CJK
  font as fallback only for Chinese characters
- Increase launcher window height from 260 to 290 to prevent bottom
  navigation buttons from being cut off
- Use ViewportCommand::Minimized instead of hide_app_window on Windows
  so the eframe event loop keeps running and tray click events are
  properly delivered for restore/quit
