fix(web,miniprogram): 端到端测试修复 + 小程序接口字段对齐

## 前端修复
- 修复 9 个 TypeScript 编译错误（未使用变量/undefined 守卫/vitest 类型）
- 重写 E2E auth fixture 使用真实 API 登录替代 mock token
- 更新 E2E 测试选择器适配当前 UI 布局
- Playwright 改为串行执行避免 token 唯一约束冲突
- E2E 测试从 0/10 通过提升到 10/10 通过

## 小程序接口一致性修复（P0-P3）
- P0: consultation.ts type→consultation_type, unread_count→unread_count_patient
- P0: followup.ts task_type→follow_up_type, due_date→planned_date, description→content_template
- P1: appointment.ts calendarView 展平嵌套结构, available_count 计算 max-current
- P1: doctor.ts HealthSummary 适配后台实际返回结构
- P2: doctor.ts PatientStats/ConsultationStats/FollowUpStats 字段名对齐
- P3: article.ts 新增 buildCategoryTree 工具函数
