Description

This PR drops dataclips when they're too big to fix #2339

Validation steps

1. Set up a workflow that creates an 11MB dataclip at some point in the workflow
2. Run it and verify that the dataclips are NOT saved for each step that's over 10MB

Pre-submission checklist

• I have performed a self-review of my code.
• I have implemented and tested all related authorization policies. (e.g., :owner, :admin, :editor, :viewer)
• I have updated the changelog.
