fix: Add Railway deployment configs and GitHub workflows

- Add Railway configuration (railway.toml)
- Add GitHub Actions workflows
  - Railway deployment automation
  - Python/Node.js testing
  - Health check monitoring
- Add GitHub templates (CODEOWNERS, PR template)
- Add requirements files if missing
- Standardize deployment across all services

This ensures consistent deployment patterns across the entire
BlackRoad OS infrastructure.
