Activate cross-chain bridge service in coordinator API

- Fix import paths in cross_chain_integration.py (relative to absolute imports)
- Add cross-chain router to coordinator API main.py
- Fix storage.db import path to use app.storage.db
- Restart coordinator-api service on aitbc
- Deploy changes to aitbc1 and restart coordinator-api
- Verify chain isolation is maintained with bridge active
- Bridge whitelist remains empty (default) - no unauthorized transfers allowed
