- Added `prop-types` for better prop validation in components.
- Introduced `CurrencyProvider` to manage currency context and preload exchange rates.
- Updated pricing logic in various components to support new price structure and display currency.
- Refactored BOMSummary, MotorStep, and PowerSupplyStep to utilize new pricing methods and improve user experience.
- Enhanced export utilities to format prices correctly in markdown and Excel outputs.
- Updated hardware and component data structures to include detailed pricing information.
