feat: 消息通知中心 + 账号安全体系 + Bug修复

## 新增功能

### 消息通知中心 (全新模块)
- 新增 MessageController / NotificationService / NotificationRepo
- SSR 消息页面 (/messages)：左侧边栏 + 右侧卡片列表，noindex 元标签
- 通知能力：列表分页、单条标为已读、一键全部标为已读
- 未读数角标 (1/66/99+)：侧边栏 + 导航栏铃铛图标
- 导航栏轮询 /api/messages/unread 每 60 秒刷新未读数
- 审核通过/驳回时自动 fire-and-forget 推送通知

### 密码修改
- ChangePassword：验证当前密码 → 新密码强度校验(8位+字母+数字) → 哈希更新
- 修改后递增 token_version 强制所有设备退登

### 账号自助注销
- DeleteAccount：验证密码 → 设置 deleted 状态 → 记录原因 → 吊销 JWT
- 注销后登录二次确认：Login 检测 deleted → 返回 confirm_restore
- ConfirmRestore 恢复账号，重新签发 token
- 注销页文案："账号将在 7 天后正式注销，期间可随时重新登录恢复"

### IP 审计记录
- 注册时记录 RegIP，登录时记录 LastLoginIP + LastLoginAt
- clientIP() 支持 X-Forwarded-For / X-Real-IP 反向代理

### 安全加固
- Login 防时序攻击：用户不存在时仍执行完整 bcrypt 比对
- FindByEmail 改用 Unscoped() 覆盖软删除用户
- 站长 (owner) 不允许自主注销，避免权限体系死锁

## Bug 修复

1. 注销按钮不触发：JS IIFE 中 profile 代码 return 阻塞了 account 标签页处理器注册
   → 拆分为两层 IIFE，profile 放在内层
2. label 缺少 for 属性导致控制台警告 → 全部补充 for 属性
3. 注销后未自动退登：DeleteAccount 只设状态未吊销 JWT → 末尾加 InvalidateSessions
4. 退登后重定向 500 panic：authenticateToken 中 err||versionMismatch 合并判断
   在 err=nil 但版本不匹配时返回 (nil,nil) → 拆为两个独立判断
   injectUserContext 增加 claims==nil / 类型断言空安全守卫
5. 注销后登录直接提示"登录成功"：FindByEmail 默认 scope 排除软删除记录
   → 改用 Unscoped()

## 文件变更
- 新建 17 个文件 (消息/审核/站点设置完整模块)
- 修改 25 个文件 (认证/设置/中间件/前端)
