Subject: [PATCH] Refactor Tender Handler to Use ListTendersRequest Struct

- Updated the GetPublicTenders handler to utilize a new ListTendersRequest struct for improved clarity and organization of parameters.
- Changed the handling of `publication_from` and `publication_to` query parameters to use pointers for optional timestamp values.
- Enhanced the service call to ListTenders, aligning with the new request structure and improving the overall code maintainability.
