feat: Runtime configuration and Docker deployment improvements

Frontend:
- Add runtime configuration service for deployment-time API URL injection
- Create docker-entrypoint.sh to generate config.json from environment variables
- Update ApiService, ApprovalService, and DocumentViewer to use RuntimeConfigService
- Add APP_INITIALIZER to load runtime config before app starts

Backend:
- Fix init-blockchain.js to properly quote mnemonic phrases in .env file
- Improve docker-entrypoint.sh with health checks and better error handling

Docker:
- Add API_BASE_URL environment variable to frontend container
- Update docker-compose.yml with clear documentation for remote deployment
- Reorganize .env.example with clear categories (REQUIRED FOR REMOTE, PRODUCTION, AUTO-GENERATED)

Workflow fixes:
- Fix DepartmentApproval interface to match backend schema
- Fix stage transformation for 0-indexed stageOrder
- Fix workflow list to show correct stage count from definition.stages

Cleanup:
- Move development artifacts to .trash directory
- Remove root-level package.json (was only for utility scripts)
- Add .trash/ to .gitignore
