feat: Add HTML report generation for test results

Add Python scripts to convert .trx test results to HTML reports:
- generate_html_report.py: Basic HTML report with test summaries
- generate_enhanced_html_report.py: Enhanced report with detailed test data
- run-tests-with-report.sh: Automation script for running tests and generating reports

These scripts parse .trx files and generate interactive HTML reports with:
- Test summary statistics (passed/failed/skipped)
- Categorized test results
- Error messages and stack traces
- Visual pass rate indicators
