feat: fix test collection and add collection stats display

- Fix collect_tests to use JSON report parsing (was returning 0 tests)
- Add Test Collection panel to testing dashboard showing total tests,
  unit/integration/performance breakdown, and file count
- Reorganize sidebar: create Platform Health section with Testing Hub,
  Code Quality, and Background Tasks
- Keep Developer Tools for Components and Icons only
- Platform Monitoring now contains Import Jobs and Application Logs
