Map all GoogleFontIconName enum values (#61)

- **Expanded and reorganized icon support:** Added many new icons (such as `queue_music`, `quick_phrases`, and Nest/network-related icons) to `GoogleFontIconName.cs` and updated summary comments for clarity.
- **Cleanup and removal:** Removed outdated/redundant icons (e.g., `pedestrian_traffic_light`, `pen_size_1`) and streamlined code for maintainability.
- **Consistency improvements:** Renamed some icons for clarity and ensured summaries are up-to-date.
- **Utility enhancements:** Updated `GoogleFontIconUtility.cs` to handle unmatched styles gracefully (returns empty string by default).
- **Demo improvements:** Updated demo Razor files to display icon counts, improved iteration logic, styling, and initialization for better consistency and UX.

**Overall:** This commit modernizes, cleans, and expands the icon enum and its utility logic, while enhancing demos for usability and clarity.
