refactor(test): migrate webdriver imports to use next.browser() method
Replace direct webdriver imports with next.browser() method calls across test files to standardize browser instance management. This refactoring improves consistency and leverages the test framework's built-in browser management.
Changes include:
- Remove webdriver import statements from test files
- Replace webdriver(next.url, path) calls with next.browser(path)
- Update browser instance initialization patterns
- Maintain existing test functionality and assertions
