录音按住松手无效根因有两处：

1. encodeBitRate:128000 对 sampleRate:16000 越界（微信规定16000Hz
  下 encodeBitRate 必须在 24000~96000 之间），导致 recorder.start()
  立即触发 onError，修改为 encodeBitRate:48000

2. uni.authorize 异步回调延迟 recorder.start()，用户松手时
  stopRecord 已执行但 recorder 尚未开始录，且之前的 recordingStarted
  守卫跳过 stopRecord 后 authorize 回调又启动录音无法停止。
  解决方案: 直接调 recorder.start()，不再前置 uni.authorize。
  微信会在需要时自动弹录音权限窗。

format 从 wav 改为 mp3（mp3 在微信各平台兼容性更好），
后端 ffmpeg 会自动转码为 wav 后再送 whisper。
