Align desktop theming around Noctalia Ayu

- Move Sway, GTK, Qt, Alacritty, and Emacs toward the Noctalia-generated Ayu theme
- Add shared font/cursor settings, qt5ct/qt6ct templates, and Flatpak theme integration support
- Keep browser and Telegram theming manual while preserving generated Noctalia assets where useful
