Refactor tender detail models and UI components for improved clarity and functionality

- Updated the `Lot`, `Organization`, and `OrganizationAddress` models to enhance data mapping for tender details.
- Revised the `TenderData` model to include additional fields reflecting the API response structure.
- Improved UI components across desktop, mobile, and tablet views by commenting out unused sections for future use.
- Added new string constants for lot details in the tender information section.
- Enhanced unit tests to cover new model fields and ensure resilience to partial API payloads.
