Initial commit: Aeroflot Flights Web - Angular 12 baseline

- Angular 12 application with PrimeNG components
- 5 existing Cypress e2e test suites
- SCSS styling with BEM naming convention
- i18n support (10 languages)
- Leaflet map integration
- Complete component hierarchy and routing structure

This baseline will be used for Angular → React migration.
