[Test] Add detailed error output for integration test failures

When rspamc commands fail, now show:
- Exit code
- Full stderr output saved to error log files
- Partial results if available
- Sample scan result for debugging

This makes it much easier to diagnose test failures instead of
just seeing 'exit code 1' with no context.
