Remove ContentXML field from Tender entity and related repository method

- Eliminated the `ContentXML` field from the `Tender` struct in the entity definition, streamlining the data model.
- Removed the `FindTendersWithContentXML` method from the `TenderRepository` interface, as it is no longer necessary.
- Updated the `ToTender` method in the `NoticeWorker` to reflect these changes, ensuring consistency across the codebase.

This update simplifies the tender data structure and repository interface, improving maintainability and clarity in the tender management system.
