feat: create shared component stubs and fix SCSS circular imports

- Created 8 core shared components: Card, PageLayout, PageTabs, DayTabs, CalendarInput, TimeSelector, CityAutocomplete, SearchHistory, PageLoader, PageEmptyList
- Fixed SCSS circular dependency: removed self-imports in components/modules-components/index.scss and modules-pages/index.scss
- Updated page exports to use feature-based implementations
- Added City interface to CityAutocomplete with mock city data
- App now loads at localhost:3001 without SCSS errors
