test: add acceptance tests for els module

- Add comprehensive acceptance tests for element(), eachElement(), expectElement(), expectAnyElement(), expectAllElements()
- Update WebElement class to handle Playwright Locator objects:
  - type() uses fill() for Locator objects
  - $() and $$() use locator() and elementHandle() methods for Locator objects
- Fix session_test.js import paths for ESM
- 30 acceptance tests + 15 unit tests passing
