Feat: Upgrade Docker deployment with multi-stage build and Nginx integration

- Upgrade Dockerfile to Go 1.24 with multi-stage build (backend + frontend)
- Add TA-Lib installation for technical analysis support
- Integrate frontend build into main container image
- Add Nginx reverse proxy configuration for API routing
- Update docker-compose.yml to simplified single-container architecture
- Update .dockerignore to include web source for build
- Improve health checks and startup time handling

Benefits:
- One-click deployment with single Docker image
- Better resource utilization with multi-stage build
- Production-ready Nginx frontend serving
- Easier maintenance and deployment
