Add Company Tender Approval Statistics Endpoint and Update API Documentation

- Introduced a new API endpoint to retrieve company-specific tender approval statistics, enhancing the analytics capabilities of the tender management system.
- Implemented the `GetCompanyTenderApprovalStats` method in the service layer to fetch detailed statistics, including total approvals, approved and rejected tenders, and submission counts.
- Updated Swagger documentation to accurately reflect the new endpoint, including detailed descriptions, parameters, and response formats for the `CompanyTenderApprovalStatsResponse`.
- Enhanced the router to include the new statistics route, ensuring adherence to Clean Architecture principles and maintaining a clear separation of concerns in the handler layer.
- Added necessary request and response forms to support the new functionality, improving the overall API structure and usability.
