Pull request overview

This PR continues the ongoing migration away from Flask-RESTX @marshal_with/api.model(...) patterns by introducing registered Pydantic BaseModel/ResponseModel schemas for the console workflow trigger endpoints, while aiming to keep the response JSON shape unchanged.

Changes:

• Added Pydantic ResponseModel response schemas for workflow trigger, trigger list, and webhook trigger responses.
• Replaced @marshal_with(...) usage with @console_ns.response(...) + explicit model_validate(...).model_dump(mode="json") serialization in the affected endpoints.
• Added unit tests covering Pydantic parsing and datetime JSON serialization behavior for the new response models.
