- Add theme store for consistent theming across application
- Improve ServiceCalendar with federal holidays and better styling
- Refactor customer profile and tank estimation components
- Update all delivery and payment pages to use centralized services
- Add utility functions for formatting and validation
- Update Dockerfiles for better environment configuration
- Enhance Tailwind config with custom design tokens

UI Improvements:
- Modern, premium design with glassmorphism effects
- Improved form layouts with FloatingInput components
- Better loading states and empty states
- Enhanced modals and tables with consistent styling
- Responsive design improvements across all pages

Technical Improvements:
- Strict TypeScript types throughout
- Better error handling and validation
- Removed deprecated api.js in favor of TypeScript services
- Improved code organization and maintainability
