refactor: improve button navigation logic with proper state detection

- Add button-wrapper element locator for accessing action/navigation buttons
- Create dedicated button objects (delete, next material, collapse)
- Add _is_button_enabled() method using Playwright's is_enabled()
- Replace index-based navigation with button state-driven loop
- Add row number change detection to wait for data loading
- Simplify navigation logic with explicit button click handling
