P0 关键修复: - P0-1: 注册接口添加 RateLimitMiddleware 限流保护 - P0-3: /metrics 端点添加 JWT 认证（移除匿名访问） - P0-4: 修复 Celery 任务名冲突（generation_task vs generate_video） - P1-5: JWT logout token 黑名单机制 P1 修复: - P1-1: forgot_password 硬编码 localhost → 使用 settings.APP_BASE_URL - P1-2: generation.py 直接创建 DB 连接 → 使用依赖注入 - P1-6: Image.open() 未关闭 → 统一使用 with 语句 - P1-7: 订阅续费事务修复 P2 代码质量: - P2-1: 修复 EditingMode 枚举重复定义 → 统一引用 shared 包 - P2-2: 修复 SMTP_FRON_NAME → SMTP_FROM_NAME 拼写 - P2-3: UserModel subscription_quota 类型统一为 float - P2-4: .env.production DATABASE_MAX_OVERFLOW 30 → 10 - 清理 15 处 except:pass（保留 2 处有注释说明的） - 禁用 SVG 上传（XSS 风险） - 删除 decode_token_unsafe() 不安全函数 - 简化 /ready 端点 - 删除 8 处死代码、10 个空文件/模块 - 合并 3 对 100% 重复函数 - 对齐 6 个废弃环境变量 v2 修复（代码审查后）: - 修复密码重置路由路径: /password/forgot → /forgot-password, /password/reset → /reset-password（与前端 API 对齐） - 合并 _check_project_access: asset_libraries.py 和 edit_plans.py 中的重复函数统一到 _helpers.py（含空字符串守卫 + 中文错误信息） - 顺手修复: HTTPException 统一从 fastapi 导入（替换 starlette 导入） - OSS_ENDPOINT 拼写修复拆分为单独 PR，本 PR 不包含
