feat(web): 首页换成和工作区同一套外壳，补上账号设置页

首页原来是居中窄栏，点进工作区又变全屏，进出像换了个网站。现在把首页也做成
全宽 + 左侧栏（SideRail 抽出来给首页和账号页共用），工作区卡片改成网格，
新建工作区是网格里的虚线卡片——宽度不再跳。

账号页 /account：基本信息（头像首字母、昵称、只读手机号、加入时间）、
登录密码（设置/修改 + 确认输入）、退出登录。工作区侧栏底部的用户块点进去就是它。

e2e account.mjs 14 项全绿，其中一条断言进工作区后侧栏宽度和首页差值 < 1px。

+## 7. 账号与外壳统一（Web，2026-10-31）
+
+### 7.1 两个问题（用户提的）
+1. 首页是"居中窄栏"，点进工作区却变成全屏——同一套产品两种壳，进出像换了个网站。
+2. 用户相关功能缺失：没有基本信息、没有改密码、没有一个统一的"退出登录"入口。
+
+### 7.2 决定
+- **外壳统一到全宽 + 左侧栏**（不是把工作区收回窄栏）：工作区里本来就要放下看板四列、知识分类树，
+  收窄是倒退。首页跟着做同样的壳，宽度就不再跳。
+- **加密码登录，作为验证码之外的第二条路**。理由：验证码依赖短信通道，通道挂了人就进不来；
+  密码是自助的第二把钥匙。但**不强制**：没设密码的人照旧只用验证码，少一道门槛。
+- 外壳抽成 `web/src/components/SideRail.tsx`，首页与账号页共用；工作区的 `AppShell` 保持自己的侧栏（有工作区切换与页签）。
+  两处宽度一致（`w-[248px]` 级别的同一份样式），所以进出不跳。
+
+### 7.3 后端
+- `app_user.password_hash`（迁移 `0008_user_password`，加列不加表）
+- `app/security.py`：scrypt（`n=2^14, r=8, p=1`，标准库 `hashlib`），存 `scrypt$n$r$p$salt$hash`；
+  `password_problem()` 一处定义强度（8–64 位、字母 + 数字）
+- `POST /auth/login/password`、`POST /auth/password`（设/改共用，改要先验旧）、`PATCH /auth/me`（改昵称）
+- 用户输出统一走 `_user_out()`：**白名单字段**，`password_hash` 一个字节都不出去；对外只给 `has_password`
+- 错误码：`2013` 密码错/没设过、`2014` 未设密码（保留）、`2015` 太弱、`2016` 连错太多
+
+### 7.4 Web
+- 首页：左侧栏 + 全宽内容区，工作区从列表改成卡片网格（`sm:2 / xl:3 / 2xl:4` 列），
+  "新建工作区"是网格里的一张虚线卡片，点开就地展开表单
+- 新增 `/account`：基本信息（头像首字母、昵称、只读手机号、加入时间）、登录密码（设置/修改 + 确认输入）、退出登录
+- 登录页：顶部「验证码 / 密码」两段切换，同一个表单两种提交
+- 工作区 `AppShell` 底部用户块可点进 `/account`，旁边一个齿轮图标
+
+### 7.5 验证
+- 后端 `pytest` → **113 passed**（新增 `tests/test_account.py` 10 项）；`ruff check` / `ruff format --check` 全绿
+- Web `tsc --noEmit` 通过、`vite build` 通过
+- 新增 e2e `web/e2e/account.mjs`（**13 项全绿**）：登录进首页 → 首页有侧栏 → 进工作区**侧栏宽度不变（差值 < 1px）**
+  → 账号页复用同一条侧栏 → 改昵称 → 设/改密码 → 刷新后仍显示"已设置密码" → 退出 →
+  错密码被拒（`2013`）→ 密码登录成功 → `/auth/me` 里 `has_password=true` 且昵称是刚改的 → 验证码登录仍可用 → 控制台零报错
+- 截图：`2.Design/screens/web-home-rail.png`、`web-account-settings.png`
+- 脚本里两个坑写进了注释：① 短信 60 秒节流会让"发码→登录"整段失败（先看 429，别怪登录）；
+  ② 改密码要先给旧密码，脚本把上一轮的密码记在 `.local/e2e-account-password.txt` 里自己维护
+
+### 7.6 没做的
+- 安卓端登录页仍只有验证码，账号页也没有——下一步对齐（密码登录 + 改昵称 + 退出）
+- 手机号换绑、头像上传未做（头像现在只有首字母）
