Add legacy data migration script and docs
...
- scripts/assign_legacy_sessions.py assigns user_id=NULL sessions,
memory_facts, and memory_summary to a target user
- Handles UNIQUE constraint conflicts in memory_facts by merging
- Merges memory_summary if user already has one
- Update docs/auth.md with legacy migration section
