生图模型可选(火山/gpt-image)+ 模特上身图提示词强化 + 多会话等改动

本轮(生图模型选择 + 火山接入):
- 工作室新增「生图模型」选择器(模特上身图/平台套图头部 chip + 图片创作底部 Pill),
  默认火山 Seedream,可切 gpt-image-2;选择写入 localStorage,下次进页面读回
- 后端 resolve_image_model 解析所选模型;enqueue_standalone_images 接 image_model
- worker 按模型能力分流:有 image_edit(gpt-image)走多图编辑;无(火山)走
  image_generation(image=参考图);新增 _ratio_to_volcano_size 让火山按比例出图
  → 内衣等敏感品类用火山可绕开 gpt-image 的 sexual 内容审核

模特上身图提示词:
- 穿戴/非穿戴分流、按 index 变化动作场景镜头、负面词尾接、多图参考序号自适应
- _product_reference_urls:商品参考真实上传图优先、排除 AI 生成图、可多张

其他(并入此前各会话未提交改动):
- 图片创作多会话(ImageConversation + migration 0019)、任务中心按类型过滤
- accounts/projects/assets/team/auth 等零散调整、相关测试
- 测试脚本(tryon_*.py)、测试清单(core/bug/*.xlsx)
