🌍 Refactor domain image logic into reusable helper function

- Moved domain image selection logic into `get_domain_image` helper for reusability.
- Simplified `app-logo-icon.blade.php` and `SeoDataAttribute` by replacing inline logic with the new helper.
- Improved maintainability and consistency for handling `lang_country` sessions.
