fix(frontend): 根治 family/member/list 与 tasks/history 重复调用——index-home loadFamilyFeed 改为只查第一个孩子、parent-index/child-index 合并 getChildren+loadFamilyMembersVisible 为单次 getFamilyMemberList

- index-home: loadFamilyFeed 从遍历所有孩子改为只查第一个孩子（避免 N 个孩子 = N 次 /api/tasks/history）
- child-index: loadData 中 getChildren() 改为 getFamilyMemberList({visibleOnly:true}) 一次调用，同步设置 familyMembersVisible，跳过后续 loadFamilyMembersVisible()
- parent-index: dashboard 成功路径同步设置 familyMembersVisible + _membersVisibleSet，降级路径合并 getFamilyMemberList+getChildren 为单次调用并派生 children
