fix: Mendix 11.9.0 integration test failures

- Update demo user password to 12+ chars (11.9.0 default policy is stricter)
- Change standalone /** doc comments to /* block comments in OData examples
  (consecutive doc comments without statements cause parse errors)
- Disable DataGrid column DROP test that depends on version-specific
  widget column naming
