后端生成闸+多项修复;前端全站更新;QA 审计与报告

后端:
- 新增 celery_health 生成前置闸——无 worker 在线时图片/视频生成入口
  一律 503,防"提交到 ARK 后无人轮询、结果悬空+额度冻结"的数据丢失
- 拼接导出:帧率跟随源众数、字幕逐句重映射、原声/BGM 混音修复
- 资金核算审计脚本 + genesis 账目回填 + 滞留预留清理命令
- 接入 yunqi provider 与豆包 TTS 模型(catalog/migrations/bootstrap 命令)

前端:全站页面更新(pipeline/library/products/projects/team/account 等),
新增共享 pager 分页组件

QA:刷新 function-audit 全量输出,新增 full-qa 报告
文档:BP 产品介绍资料、design/CLAUDE.md

+"""Celery worker 在线探测 —— 生成类任务的提交前置闸。
+
+设计决策(2026-06-10):无 worker 时**禁止提交**图片/视频生成,而非静默降级到前端轮询。
+旧行为的风险:提交到 ARK 后浏览器一关就无人轮询,生成结果悬在云端无人取回入库、
+额度预扣长期冻结——等于数据丢失。额度预检挡"钱不够",这道闸挡"环境不齐"。
+
+探测用 control.ping 广播,结果带缓存:在线缓存 30s(别让每次提交都付 ping 开销),
+离线只缓存 5s(worker 一启动尽快解封)。CELERY_TASK_ALWAYS_EAGER(测试/同步模式)
+下任务就地执行不需要 worker,直接放行。
