feat(core): 基础资产 Agent 化 — 商品三视图(image_edit 参考主图)+ 人物立绘/三视图异步生成 + 演员库/详情

- 商品三视图:有真实商品主图时走 image_edit,以主图为参考锁包装一致(品牌字/配色/外形/Logo)
- 人物:据「某一版立绘」异步生成配套三视图(image_edit,worker 内跑),立绘/三视图各存版本可切换
- 基础资产出图改异步(run_base_asset_task / generate_triview_task),Web 层不被慢出图占住
- 前端:演员库浏览/新增、人物详情(立绘+三视图+版本切换/下载/查看大图)、按 busyKey 的单卡并发 loading(genBusy,替代全局 genBusyKey,各按钮互不阻塞)
- dev:本地连云端 MySQL 复用连接(CONN_MAX_AGE/health check/connect_timeout),仅 development 生效
- 含 projects 测试补充

tsc + py_compile + 26 后端测试通过。
