Enhance Tender Management with Company-Based Matching and API Updates

- Updated the tender service to include company-based matching for tenders, allowing for more relevant results based on company CPV codes.
- Modified the ListTenders endpoint to accept a company ID parameter for calculating match percentages and sorting tenders accordingly.
- Refactored the tender response structure to include match percentage and days until deadline for better client-side handling.
- Updated API documentation to reflect changes in the tender listing functionality and added new endpoints for public tender access.
- Removed deprecated customer-related methods and streamlined customer listing functionality for improved clarity and performance.
