feat: Add real-time warehouse statistics with daily changes for fulfillment centers

- Added new GraphQL query `GET_FULFILLMENT_WAREHOUSE_STATS` to fetch warehouse statistics with daily changes
- Created comprehensive GraphQL resolver `fulfillmentWarehouseStats` that calculates:
  * Current quantities for products, goods, defects, pvzReturns, fulfillmentSupplies, sellerSupplies
  * Daily changes (absolute numbers) based on deliveries in the last 24 hours
  * Percentage changes for all categories
- Updated fulfillment warehouse dashboard to use real GraphQL data instead of static calculations
- Added polling every 60 seconds to keep statistics up-to-date
- Enhanced StatCard component to display accurate percentage and absolute changes
- Statistics now show real supply deliveries and changes relative to the previous day
