feat: iOS 审核阉割版 - iOS 蓝牙功能屏蔽 + Info.plist 删蓝牙权限 + AI 提示词去医疗化（应对 App Store 1.4.1）

- iOS 蓝牙 UI 入口用 Platform.isIOS 屏蔽（抽屉/设置页/记数据卡片/AI 嵌入链接）
- Info.plist 删除 NSBluetoothAlwaysUsageDescription 和 NSBluetoothPeripheralUsageDescription
- AI 提示词重写：只描述客观事实和综合信息，不给医疗建议，不做关联性分析/推测
- 所有"专家/教练/预问诊/预解读"角色改为"记录/整理/结构化提取助手"
- 去掉基于疾病（冠心病/糖尿病等）的饮食运动建议
- 保留正常值参考范围用于客观描述"超出范围"，不作诊断
