Update database paths and fix foreign key references across coordinator API

- Change SQLite database path from `/home/oib/windsurf/aitbc/data/` to `/opt/data/`
- Fix foreign key references to use correct table names (users, wallets, gpu_registry)
- Replace governance router with new governance and community routers
- Add multi-modal RL router to main application
- Simplify DEPLOYMENT_READINESS_REPORT.md to focus on production deployment status
- Update governance router with decentralized DAO voting
