Add basic UI components for web application

- Set up Tailwind CSS configuration for styling
- Create Button component with variants (primary, secondary, outline, ghost, danger)
- Create Input component with label, error, and helper text support
- Create Card component with composable subcomponents (Header, Title, Description, Content, Footer)
- Create LoadingSpinner component with size and fullscreen options
- Create ErrorMessage component with retry and dismiss actions
- Add comprehensive test suite using Jest and React Testing Library
- Configure ESLint and Jest for quality assurance

All components follow consistent design patterns from mobile app
and include proper TypeScript types and accessibility features.
