fix: Mendix 10.24 nightly failures and version compatibility docs

Nightly integration tests for Mendix 10.24 failed because widget
templates (from 11.6) and 11.x-only MDL features were not gated.

Changes:
- Gate 17-custom-widget-examples and 19-image-collection-examples
  to 11.0+ (pluggable widget template tests)
- Gate P040_ConditionalProps section in 03-page-examples to 11.0+
  (Visible/Editable xpath syntax)
- Add CE0463 as global known error (widget template version mismatch)
- Update nightly/push-test to use Mendix 11.9.0 (latest release)
- Add conditional visibility/editability and responsive column widths
  to version registry YAML files
- Expand version-compatibility docs with fine-grained feature matrix
