style: auto-format with black + isort + ruff + prettier [skip ci-format-check]

根因：#2200重写V2时把 prompt_loader 调用链删了，system/user prompt
全部硬编码在 vlm_fast_json.py / vlm_fallback.py，用户在后台管理端
配置 viral_video_prompt_templates 表 prompt_type='image_analysis' 的
自定义提示词完全没被读取。

修复：
- 新增 vision/_prompt.py，复用 packages.application.viral_video.prompt_loader
  读取后台 image_analysis 配置，30秒TTL热加载
- 判定策略：读到的system_prompt以默认XML模板开头（'你是电商商品视觉分析师'）
  视为内置默认→使用硬编码JSON schema；否则视为用户自定义→使用用户
  system_prompt并在末尾追加JSON硬约束'你必须只返回一个合法的JSON对象...'
- user_prompt同理：用户模板存在就渲染（image_count=1/industry=通用/image_urls留空），
  不存在用硬编码默认
- DB不可用/读取异常→静默fallback到硬编码JSON prompt，不阻断流程
- fast路径(qwen3.8-flash)和pro路径(qwen3.7-plus)都接入_resolve

本地冒烟：DB不可用时fallback到默认JSON prompt正常；pro兜底返回pp质量良好。

Refs: 用户反馈后台配置提示词无效

+"""V2 快速路径：qwen3.8-flash（阿里云百炼/DashScope）强约束 JSON-only 调用。
+
+目标：替代"人体属性/商品检测/图像标签"三个火山不存在的专用云端 API。
+设计要点：
+- 直接用 httpx 发最小 payload 到 DashScope OpenAI 兼容 endpoint，不走 ai_client 包装
+- enable_thinking=false 关闭推理链（reasoning 是延迟主因）
+- response_format=json_object 强约束JSON输出
+- system prompt 优先读后台 viral_video_prompt_templates 配置，DB不可用时fallback到硬编码JSON schema
+- max_tokens=350、temperature=0.1（稳定输出 JSON）
+- timeout=12s（失败由外层走 pro 兜底）
+- API Key 从环境变量 DASHSCOPE_API_KEY 读取
