feat(mp): AES-256-GCM 加密存储 + 安全日志 + ErrorBoundary 升级 + BLE 并发修复

- secure-storage-aes: AES-256-GCM 替代 XOR，保留 XOR 迁移读取
- crypto-polyfill: wx.getRandomValuesSync → crypto.getRandomValues
- logger.ts: dev/prod 区分日志级别，生产不输出详情
- ErrorBoundary: 错误分类(network/render/unknown) + 结构化日志
- DataSyncScheduler: isSyncing 互斥防并发重复同步
- app.tsx 首行导入 crypto-polyfill
