feat(personal_collect,motion_reminder): 新增回收站与云端TTS语音功能
- 新增小程序个人收藏回收站页面，支持查看已删除收藏、恢复与彻底删除操作 - 修复个人收藏文件上传时的中文名乱码问题，新增原文件名透传参数 - 接入阿里云百炼TTS服务，实现运动提醒模块的云端语音合成与本地缓存，支持系统TTS与云端MP3双降级播放 - 新增语音引擎探测与异常预警UI，覆盖web端与移动端 - 优化web端订单盒页面布局，修复卡片操作按钮换行问题 - 新增调试探针脚本、ESLint配置与相关lint脚本 - 完善后端接口与路由，更新项目依赖与配置文件

// 运动提醒宝（motion_reminder）语音播报：系统 TTS + 云端 mp3 双通道兜底
|
||||
// 说明：项目 Rule 6 要求每个 tool 独立维护自己的第三方能力封装，
|
||||
// 因此本文件不引用其他 kit 的语音实现，只依赖本 kit 的 ./api 与 expo-av / expo-speech。
|
||||
// 场景：安卓设备无系统 TTS 引擎、引擎被回收、或系统 TTS 静默失败时，改播服务端预合成的 mp3。
|
||||
// 语义与 Web 端 order_box.js 语音区保持一致：探测 → 预合成 → 运行期自动降级 → 不可用预警。
