Fix Stylix conflicts: disable KDE target, remove i3 keybinds, simplify theming

- Disable Stylix's automatic KDE target to prevent file conflicts
- Remove all i3-style keyboard shortcuts from KDE configuration
- Remove custom color definitions from kdeglobals (let Stylix handle colors)
- Simplify kdeglobals to only set dark theme (Breeze Dark)
- Simplify kwinrc to minimal compositing settings
- Remove custom Konsole color schemes (Stylix handles terminal theming)
- Add menubar hiding for all common KDE applications (konsole, dolphin, kate, gwenview, spectacle, ark, okular)
