refactor(TenderDetails): enhance country flag handling and validation

- Updated the TenderDetails component to validate country codes using a new utility function, isValidAlpha2CountryCode.
- Modified the useGetFlagQuery hook to accept an options parameter for conditional fetching based on the validity of the country code.
- Improved the rendering logic for the country flag to ensure it only displays when valid flag data is available.
