🌐 Introduce dynamic domain-based locale and country handling

- Added `DomainMiddleware` to dynamically set locale, language-country session, and app name based on domain.
- Updated views and components to leverage `lang_country` session for language and region-specific content.
- Enhanced country parameter retrieval with `config('app.domain_country')` as fallback.
- Refined language filtering by scanning available language files dynamically.
- Added language-specific assets and translations (`nl.json`, `es.json`) with improved language-region associations.
- Updated `app-logo-icon` to display region-specific images or default SVGs.
- Improved views with cleaner, dynamic rendering and session-aware functionalities.
