Enhance CountryFlag to accept country names and codes

- Add actualCountryCode computed property to handle both 2-letter codes and country names
- Extend parseCountryInput with common country name variations (USA, UK, etc.)
- Import parseCountryInput utility in CountryFlag component
- Update template to use actualCountryCode instead of direct countryCode prop
