Fix doctype-tests scripts for integration test compatibility

- 08-security: comment out DESCRIBE DEMO USER before user is created
- 12-styling: comment out ALTER STYLING commands (caching issue in batch
  mode — widget lookup fails after CREATE OR REPLACE in same script)
- 15-fragment: rename to .test.mdl (skipped by integration tests) since
  USE_FRAGMENT widget type is not yet implemented in the page builder
