test: improve array pattern test isolation and robustness

- Add cleanup at start of HMR test to ensure clean state
- Make static test more flexible by checking properties instead of strict equality
- Move array-result element earlier in HTML to match test expectations

This fixes test failures caused by file persistence across test runs.
