refactor(server): 调整 Docker 运行架构为 Next.js 代理 Go API

- 修改 Dockerfile 中的运行命令，将 Next.js 设为对外服务，Go 服务在内部监听
- 更新端口配置，后端监听端口从 3000 改为 80
- 移除 Go 服务中的反向代理逻辑，统一由 Next.js 处理页面请求
- 修改 Next.js 配置，在生产环境中也启用 API 代理功能
- 更新文档描述，明确 Next.js 作为页面入口，API 请求代理到 Go 服务
- 调整开发环境端口配置，web 开发端口从 3001 改为 3000
- 更新版本号至 v0.0.4 并修改 CHANGELOG
