Store DAM metadata JSON in database description field + test Box template

Database:
- Store full DAM metadata JSON in description field (5KB limit)
- Includes Box links and upload folder ID
- Full asset metadata preserved

Box Metadata Template Testing:
- Simplified to send just test string first
- Log endpoint and values being sent
- Try 5 field name variations
- Will identify correct field name from logs

Next test will show which field name works for Box template.
