用户要求：内测的固定验证码 123456 等于"知道手机号就能进任何账号"，先关掉； 登录改用账号密码，并多一种"邮箱当账号名"的方式；发信邮箱要能在后台改。 短信那条路（默认关）： - `SMS_LOGIN_ENABLED=false`，`/auth/sms/send` 与 `/auth/login` 统一回 2017，不是静默失败； - 生产校验改成"开着短信登录就必须配真通道"，不开时 provider 是 dev 也不拦； - 新增 `GET /auth/methods`，登录页据此渲染，关着的路不出现（少一次"点进去才发现不能用"）。 邮箱登录： - `app_user.email` + `uq_app_user_email`（`lower(email)` 部分索引），登录与绑定都归一成小写； - `POST /auth/login/password` 收 `phone` 或 `email`（二选一），失败统一 2013、连错 10 次锁 15 分钟； - 绑定在 `PATCH /auth/me`：格式错 2018、被占用 2019、留空串表示解绑。 系统设置（跨租户，只有平台管理员能改）： - 新表 `system_setting`（不挂租户、无 RLS，写权限由 `deps.platform_admin` 把关）； - `GET/PUT /settings/smtp`、`POST /settings/smtp/test`，授权码只写不读，留空表示沿用旧值； - `services/mail.py` 只用标准库 smtplib：465 走 SSL、587 走 STARTTLS，认证/拒收/网络失败都归 2020 但消息不同； - Web 新增「系统设置」页（状态卡 + 测试发信），侧栏只对平台管理员显示入口；账号页补「邮箱」。 验证：pytest 130 passed、ruff check/format 全绿、tsc 通过、vite build 通过； `web/e2e/login-email-smtp.mjs` 15 项全绿（含用 126 授权码真发一封测试邮件）。 顺带记下的两个坑：`platform_admin_phones` 是 list，pydantic-settings 会按 JSON 解析， 要用 `NoDecode` 交给 before-validator 拆逗号；迁移号写成 0009 会撞既有的 0009，一并改成 0010。
