fix(health): 修复选择规划师页调用available-guides缺少packageId报错

teacher-service.vue 误用 getAvailableGuides(packageId) 接口（传空对象导致
packageId 缺失报错，且返回字段 guideId/nickname 与页面模板 id/name 不匹配）。
改用后端已有的 /api/health-plan/available-teachers 接口，返回 id/name/isBound
等字段，与页面模板完全匹配。api.js 新增 getAvailableTeachers(familyId) 封装。
