Enhance FlowComponentInfo with timestamp and utility function

This commit updates the FlowComponentInfo class to include a validated_at field that stores the current timestamp in ISO format. A new utility function, get_datetime_now, is introduced to retrieve the current UTC time. Additionally, the ingestion validation logic is refined to include a check for OpenAI embeddings, improving the overall validation process.
