cleanup: Backend Phase 1 — 5项代码清理任务

1. 修复密码重置接口路径不一致 Bug (auth.py)
   - forgot_password 硬编码 localhost → 使用 APP_BASE_URL 配置

2. 删除 8 处死代码（未使用 import/变量）
   - 清理多个文件中的未使用导入和变量

3. 删除 8 个空文件/空模块
   - 删除无内容的 __init__.py 文件

4. 合并 3 对 100% 完全重复的函数
   - 提取 check_project_access/get_user_plan/require_project_and_library
   - 新建 apps/api/app/api/routes/_helpers.py 作为共享模块
   - 6 个路由文件改为从 _helpers 导入

5. 对齐 6 个废弃/异常环境变量
   - 修复 DATABASE_POOL_RECYLE 拼写错误 → DATABASE_POOL_RECYCLE
   - 添加 JWT_ALGORITHM/JWT_ACCESS_TOKEN_EXPIRE_MINUTES/JWT_REFRESH_TOKEN_EXPIRE_DAYS 到 Settings
   - 修复 jwt_service.py hasattr 字段名匹配
   - .env.example: CORS_ORIGINS → CORS_ORIGINS_RAW（逗号分隔格式）
   - .env.example: 启用 APP_ENV
   - 修复 OSS_ENDPOINT 默认值拼写错误 (aliiyuncs.com → aliyuncs.com)
   - 添加 COSYVOICE_* 变量来源注释

修改文件: 52 个（新增 1，删除 8，修改 43）
