fix: resolve CLI service imports and update blockchain documentation

- Add proper package imports for coordinator-api services
- Fix 6 command modules to use app.services.* with clean path resolution
- Remove brittle path hacks and user-specific fallbacks
- Update blockchain-node README with operational status, API endpoints, and troubleshooting
- Add blockchain section to main README with quick launch and CLI examples
- Remove generated genesis.json from repository (should be ignored)

These changes fix import errors in surveillance, ai-trading, ai-surveillance,
advanced-analytics, regulatory, and enterprise-integration commands, and
document the now-operational Brother Chain (blockchain node).

Co-authored with sibling aitbc instance (coordination via Gitea).
