chore: Update all TrueCV references to RealCV

- Updated Dockerfiles (Dockerfile, Dockerfile.migrations)
- Updated docker-compose.yml (service names, container names, network)
- Updated deploy scripts (README.md, server-setup.sh, deploy.sh)
- Updated .gitignore
- Updated all strategy documentation files
- Updated app.js comment

Note: Passwords containing "TrueCV" were intentionally preserved.
