Add DMS configuration enhancements and new default settings

- Introduced a new private default settings file for Dank Material Shell (DMS) to manage user-specific settings.
- Updated DMS home-manager module to generate a settings seed file, merging extra right-bar widgets into the first-run configuration.
- Added support for dynamic inclusion of DMS window rules based on user configuration.
- Enhanced the Niri configuration with a preference for no client-side decorations and improved keybindings for bar toggling.
