fix(mp): T40 UI 审计修复 — 28 项设计系统合规 + 安全加固 + 讨论记录

T40 UI 审计修复（60 页面全覆盖）:
- 新增 $acc-d/$wrn-d 渐变中间色变量，修复首页轮播渐变硬编码
- 替换 8 处裸 white 为 $white 设计变量（5 个 SCSS 文件）
- 修复 7 处触摸目标 40/44px → 48px（健康/消息/咨询/预约/首页）
- 3 页面新增 Loading 状态（体征录入/个人中心/就诊人添加）
- statusTag 移除硬编码布局值，改用 SCSS mixin 控制
- 医生端 14 页面架构 Hook 层补充（useThrottledDidShow 替换 useEffect）
- 移除 action-inbox 未使用 import

安全 P0 修复:
- JWT 中间件加固：token 类型校验 + 过期预检 + 类型别名简化
- 速率限制增强：滑动窗口 + 暴力破解防护
- analytics handler 错误处理完善

文档:
- T40 审计报告（24 PASS / 36 PASS_WITH_ISSUES / 0 NEEDS_WORK）
- 5 份 DevTools/性能审计讨论记录
- wiki 症状导航 + 小程序章节更新
