fix(health): 修复患者端咨询权限+聊天页UI+SVG模板警告

- consultation_handler: create_message/mark_session_read 从 .manage 降为 .list，
  患者端只有 list 权限，导致发送消息和标记已读 403
- consultation.ts: 同步后端 DTO doctor_name/patient_name 等缺失字段
- messages/index.tsx: 咨询卡片显示医生姓名替代 consultation_type
- consultation/index.tsx: 同步显示 doctor_name
- pkg-consultation/detail: 按原型重写聊天页（医生头像+在线状态+非对称气泡+药丸输入栏）
- ProgressRing: SVG 替换为 conic-gradient 纯 CSS，消除 tmpl_0_svg 模板警告
- usePageData: stopPullDownRefresh 加 try-catch 防止 DevTools fd race
