fix: 邮件懒加载、cloudEnabled 刷新、邮箱写入时机、验证码重发冷却

- server/lib/email.ts: transporter 改为懒加载，避免 ESM import 提升导致 EMAIL_PASS 未加载
- server/routes/auth.ts: send-verify 改为写 pendingEmail，验证成功后才写 email；新增 60s 冷却；catch 块打印错误
- server/db.ts: 新增 pendingEmail 字段及迁移
- src/stores/appStore.ts: 新增 refreshCurrentUser，启动时调用 apiGetMe 拉取真实 cloudEnabled
- src/App.tsx: 启动时调用 refreshCurrentUser
- ProfileModal/AccountModal: 加入 60s 倒计时和重新发送按钮
