Synchronize YAML Configurations to VueGraph Database

This tool uploads local YAML workflow configurations from the yaml_instance/
directory to the VueGraph database via the API endpoint. This is essential for
making workflow configurations available to the frontend visualization system.

Purpose:
- Ensures the database reflects the latest YAML configurations
- Required after modifying workflow YAML files to see changes in the UI
- Useful for development and deployment workflows

Usage:
    python tools/sync_vuegraphs.py
    # or via Makefile:
    make sync
