feat(voice): 大神语音介绍真实落地（录制/上传/试听）

- DB: companions.voice_intro_url；仓储 updateCompanionVoice；详情与 /api/expert/me 返回 voiceIntroUrl/voiceDuration
- 后端: POST /api/companions/:id/voice（音频白名单 mp3/m4a/aac/wav/ogg、5MB、≤60s、限流、仅本人或管理员）
- 小程序: api.uploadVoiceIntro（uni.uploadFile + 用户令牌）；工作台新增「语音介绍」卡片（录制/重录/试听，60s mp3）；详情页改为 uni.createInnerAudioContext 真实播放，卸载销毁
- 修复 uploadImage 未携带用户令牌（生产 fail-closed 后会导致上传失败）
- 新增 voice-intro.spec.ts（104 套件/701 用例全绿）；冒烟 7/7
