refactor: restructure test utilities and enhance context view tests

- Refactored test utilities by consolidating and organizing helper functions into dedicated modules for better maintainability and clarity.
- Introduced new utility functions for interactions, waiting, and element retrieval, improving the readability of test cases.
- Updated context view tests to utilize the new utility functions, enhancing test reliability and reducing code duplication.
- Removed deprecated utility functions and ensured all tests are aligned with the new structure.
