feat: 实现内容系统 MVC（Post CRUD + 审核流转）

按 content-system.md 设计文档，实现帖子内容系统的最小可行 MVC。新增： - Model: Post 模型，含 5 种状态（draft/pending/approved/rejected/locked） - Repository: post_repo.go，分页查询（前台 approved 列表 + 后台全状态筛选） - Service: post_service.go，核心业务逻辑（状态流转、Markdown 渲染 Goldmark） - Controller: post_controller + admin_post_controller，SSR 页面 6 个 + API 13 个 - Template: 列表/详情/编辑器/404 + 管理员列表，各配 CSS/JS - 路由: /posts, /posts/:id, /posts/new, /posts/:id/edit, REST API, Admin API - gomod: + github.com/yuin/goldmark v1.8.2 修改： - Main: AutoMigrate Post 表 - Router: deps 注册 PostService/Controller，路由注册 - Nav: 新增“帖子”导航链接 - Admin Sidebar: 新增“内容管理”入口设计： - 审核开关复用 audit.enabled，开启时帖子为 draft，关闭后直接 approved - 仅 approved 公开可见，作者/admin 可预览非公开状态帖子 - 严格分层 ISP 接口: Controller → postUseCase, Service → postStore, Repo → *PostRepo - 状态保护: pending/locked 禁止编辑，rejected 编辑后自动重置为 draft
