Enhance product price retrieval by including currentRegionId in FalukantController and FalukantService

- Updated the FalukantController to accept currentRegionId as a parameter for fetching product prices in cities.
- Modified the FalukantService to incorporate currentRegionId in the price calculation logic, allowing exclusion of the current region from results.
- Adjusted frontend components to pass currentRegionId, improving the accuracy of price comparisons and user experience.
