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）

+# CI 必需环境变量清单
+
+> 本文档整理小虾 SaaS 项目中所有从环境变量读取的配置项，明确哪些是 CI 测试必须的、哪些是可选的。
+> 最后更新：2026-07-09
+
+## 目录
+
+- [一、配置来源说明](#一配置来源说明)
+- [二、CI 必需环境变量（P0）](#二ci-必需环境变量p0)
+- [三、可选环境变量（有默认值）](#三可选环境变量有默认值)
+- [四、测试专用环境变量](#四测试专用环境变量)
+- [五、Worker 服务环境变量](#五worker-服务环境变量)
+- [六、当前 CI 配置对照](#六当前-ci-配置对照)
+
+---
+
+## 一、配置来源说明
+
+项目的环境变量配置主要来自以下几处：
+
+| 来源 | 文件路径 | 说明 |
+|------|---------|------|
+| API 主配置 | `apps/api/app/config.py` | pydantic `Settings` 类，API 服务核心配置 |
+| Worker 配置 | `apps/worker/worker_app/core/config.py` | pydantic `WorkerSettings` 类，Worker 服务配置 |
+| 共享配置 | `packages/shared/config.py` | pydantic `SharedSettings` 类，API + Worker 共享配置 |
+| 直接读取 | 各模块中 `os.environ` / `os.getenv` | 散落在各业务模块中的直接读取 |
+
+> **注意**：pydantic-settings 配置默认 `case_sensitive=False`，即环境变量名不区分大小写，但习惯上使用大写。
+
+---
+
+## 二、CI 必需环境变量（P0）
+
+以下变量是 CI 运行测试**必须配置**的，缺失会导致测试启动失败或核心功能异常。
+
+| 变量名 | 用途说明 | 默认值 | 影响范围 |
+|--------|---------|--------|---------|
+| `DATABASE_URL` | 数据库连接字符串 | `postgresql+psycopg://postgres:postgres@localhost:5432/xiaoxia_saas` | 集成测试、 Alembic 迁移验证 |

+| `JWT_SECRET_KEY` | JWT 签名密钥，**无安全默认值**，必须显式设置 | `None`（启动校验失败） | 所有涉及认证的 API 测试 |
+
+> **说明**：
+> - 单元测试通过 `USE_IN_MEMORY_DB=true` 使用 SQLite 内存数据库，无需 PostgreSQL
+> - 集成测试需要真实 PostgreSQL，需设置 `DATABASE_URL`
+> - `JWT_SECRET_KEY` 在测试文件中通过 `os.environ.setdefault()` 设置了测试用默认值，CI 中可不额外配置，但生产环境必须配置

+| `JWT_SECRET_KEY` | （未配置） | ⚠️ 测试内置 | 测试文件中通过 `setdefault` 设置了测试密钥 |
+
+### 6.1 CI 环境变量现状评估
+
+- ✅ **数据库配置完备**：DATABASE_URL + USE_IN_MEMORY_DB 已正确配置
+- ✅ **JWT 密钥**：测试代码内置默认值，CI 可正常运行
+- ⚠️ **缺少 Redis 配置**：但当前测试不依赖 Redis，使用默认值即可
+- ⚠️ **缺少邮件/OSS/语音配置**：均为可选，CI 中使用空默认值不影响核心测试
+
+### 6.2 建议后续补充
+
+如果未来测试覆盖到以下功能，需要在 CI 中补充对应配置：
+
+1. **Redis 相关测试** → 配置 `REDIS_URL`
+2. **邮件发送测试** → 配置 `ENABLE_EMAIL_DELIVERY` 及 SMTP 相关变量
+3. **OSS 上传测试** → 配置 OSS 相关变量（或使用 mock）
+4. **语音合成测试** → 配置 CosyVoice 相关变量（或使用 mock）
