feat(hyprland): add hyprland configuration with keyboard layout injection and vm compatibility

Add Hyprland desktop environment support with:

- New hyprland.conf template with keyboard layout placeholders (__KB_LAYOUT__ and __KB_VARIANT__) that get injected during installation
- Hyprland wrapper script (/usr/local/bin/fws-hyprland) that detects virtual machines and forces software rendering to prevent compositor crashes on virtual GPUs (VMware vmwgfx, VirtualBox)
- Automatic configuration deployment to /etc/skel and existing user home directories
- Refactored keyboard layout detection logic (moved to section 3bis) to support both X11/SDDM and Hyprland configurations
- Added locale generation during installation to ensure proper language support

Keyboard layout is now derived from either kickstart configuration or system locale using langtable, providing consistent keyboard behavior across all desktop environments.
