refactor(tender-details): enhance translation page tests and layout

- Updated Cypress tests for the tender translation page to improve visibility checks and streamline assertions.
- Refactored test structure to utilize a dedicated function for fetching the visible title heading.
- Adjusted test cases to ensure accurate language switching and URL handling for tender details.
- Improved layout consistency in the translation page by refining element visibility checks and ensuring proper section rendering.
