refactor: modularize Hyprland configuration

- Create home/hyprland/default.nix module with configurable options
- Add support for monitors, extraEnv, streamcontroller, lockhelper, grimblast, wacom
- Add workspace strategy (numbered vs named per monitor)
- Update magicman config to use new module with minimal config
- Update gunter config to use new module with all customizations
- Remove deprecated Hyprland config files
- Significantly reduce duplication between host configs
- Both configurations build successfully
