Docs: Add Docker one-click deployment support for all languages

Complete Docker deployment solution with beginner-friendly documentation:
**New Docker Files:**
- `Dockerfile` - Multi-stage Go backend build with health checks
- `web/Dockerfile` - Frontend build with Nginx and API proxy
- `docker-compose.yml` - Full orchestration with service dependencies
- `.dockerignore` & `web/.dockerignore` - Build optimization
- `start.sh` - Convenient management script (start/stop/logs/status)
**Comprehensive Documentation:**
- `DOCKER_DEPLOY.md` (中文) - Complete Chinese deployment guide
- `DOCKER_DEPLOY.en.md` (English) - Complete English deployment guide
  - Prerequisites & Docker installation (macOS/Windows/Linux)
  - 3-step quick start (config → start → access)
  - Service management commands
  - Advanced configuration (ports, resources, env vars)
  - Data persistence & backups
  - Comprehensive troubleshooting
  - Security recommendations
  - Production deployment (Nginx, HTTPS, Docker Swarm)
  - Monitoring & logging setup
**README Updates (All 4 Languages):**
- README.md (English)
- README.zh-CN.md (中文)
- README.uk.md (Українська)
- README.ru.md (Русский)
Added prominent "Option A: Docker One-Click Deployment" section at the
beginning of Quick Start in all languages. Clearly marked as EASIEST
method for beginners. Shows 3 simple steps with command examples and
links to detailed DOCKER_DEPLOY docs.
**Key Features:**
- One-command deployment: `./start.sh start --build`
- Auto-handles all dependencies (Go, Node.js, TA-Lib)
- Health checks for both services
- Data persistence (logs, cache, config)
- Log rotation (10MB × 3 files)
- Easy service management
- Beginner-friendly for complete newcomers
**User Benefits:**
- No need to install Go, Node.js, or TA-Lib manually
- Works on macOS, Windows, Linux
- Perfect for non-developers
- Production-ready with best practices
This makes NOFX truly accessible to beginners as requested: "真就让小白都能一键开始"
