Enhance event registration system:

- Update Google Sheets integration to support optional tab names.
- Add functionality to fetch and display public participants.
- Revise event configuration in YAML for clarity and consistency.
- Improve form layout with additional fields for contact information and meal preferences.
- Create a new home page template for event selection.
- Update success page to link back to the participants list.
