Issue: After fixing the description field removal, integration tests
started failing with "must have required property 'settings'" error.
Root cause: n8n API requires the settings property to be present in
workflow updates, but we were deleting it when no settings were
provided or when all settings were filtered out.
Solution: Instead of deleting settings, provide minimal valid default
settings (executionOrder: 'v0') to satisfy n8n API requirements while
avoiding "additional properties" errors.
This fixes both issues:
- Original #431: Empty settings {} causes "additional properties" error
- New issue: Missing settings causes "required property" error
Updated tests to expect minimal default settings instead of no settings.
