refactor: 录音换成微信同声传译插件

替换整个录音+ASR流程:
- 移除 uni.getRecorderManager() + 后端上传 ASR 方案
- 接入 WechatSI 插件 getRecordRecognitionManager()
- start() 一次性完成录音+实时流式识别
- onRecognize 实时回填 inputText (用户可见)
- onStop 自动调用 sendAnswer()，无需手动点击发送
- 移除 asrLoading/skipAsr/recorderStarted/pendingStop 状态

效果: 8步→3步, 延时2-10s→~500ms, 不再有录音格式兼容问题

注意: 需在 mp.weixin.qq.com 后台添加同声传译插件(插件ID: wx069ba97219f66d99)
