Fix iOS/macOS test coverage extraction in CI

- Add debugging steps to diagnose why coverage shows 0%
- Implement multiple fallback methods for coverage extraction:
  1. Standard xccov with --json flag
  2. Text parsing fallback without --json
  3. Test execution verification (0.1% if tests ran but coverage failed)
- Fix command order: put --json flag after xcresult path
- Add detailed logging to understand coverage extraction failures
- Check xcresult contents with xcresulttool for coverage data

This should resolve the "Failed to load coverage report" errors
and provide better visibility into what's happening in CI.
