debug(douyin): staging 临时开启 DOUYIN_DEBUG_ERRORS 暴露原始错误以定位 503 根因

- scripts_ai.py: 加 DOUYIN_DEBUG_ERRORS 开关（staging env 开启），错误 detail 附带 yt-dlp 原始错误前 300 字符 - _dbg helper + cookies 路径/字节数日志 - .env.staging: DOUYIN_DEBUG_ERRORS=true（定位完成后关闭）
fix(douyin): 升级 yt-dlp>=2026.8.19 + 桌面浏览器 UA/Referer 绕过抖音反爬
