上一版把明文密码换成随机生成时，引入了三个问题。都是我自己的补丁
造成的，而且症状都像"功能坏了"，实际是环境和脚本的问题。
== bug 1：兜底替换把函数调用塞进了字符串 ==
fix_hardcoded_password.py 里有句兜底：
text = text.replace(OLD, '_admin_password()')
而原代码是：
{"username": "xmz7891", "password": "@<老密码>"}
^ @ 在引号**里面**
正则要求引号紧贴老密码，这里中间有个 @，所以没匹配上；
兜底替换就把老密码换成了函数调用，结果成了**字符串字面量**：
{"username": "xmz7891", "password": "@_admin_password()"}
7 个文件被这样弄坏。它们拿这串东西当密码去登录，
当然登不上 -> 401「请先登录」-> 管理接口测试全红（12 项失败）。
教训：**批量替换里的兜底 str.replace 太危险**，它不看上下文。
替换完必须检查有没有"函数调用被引号包起来"这种形状。
== bug 2：测试和它自己起的中转对不上密码 ==
密码改成随机生成之后，测试分成两边：
* 测试进程：_admin_password() 去环境变量/文件里找
* 它启动的中转：找不到就随机生成一个
两边不一致 -> 登录失败。
修法：测试在**模块级**（import 时）生成一个本次运行专用的随机密码，
写进 os.environ["RELAY_ADMIN_PASSWORD"]。测试启动中转用的是
dict(os.environ)，所以会自动传过去 —— 两边就是同一个密码。
用随机而不是写死：写死就又变成"密码进仓库"了，白改一场。
== bug 3：全新部署启动后没有密码文件 ==
admin_password() 原来只在有人访问登录页时才调用，于是全新部署
启动后 data/admin_password.txt 一直不存在，日志里也看不到密码，
管理员不知道该用什么登。
修法：main() 里在 admin_key() 后面补一句 admin_password()，
和钥匙一样的道理 —— 启动时生成并打印一次。
== 验证 ==
管理页设备控制 23/23 通过
管理页批删 24/24 通过
管理页按钮 10/10 通过
管理页 JS 通过
管理页网络体检 15/15 通过
密码随机生成 11/11 通过（含"老密码登不进去"、"两次部署密码不同"）
工作区搜不到明文密码了（git 历史里还有，等用户确认后重写）。

"""验证中转管理页的两台设备控制功能。
|
||
|
||
要验证：
|
||
A. 「允许新设备接入」开关
|
||
1. 接口 /v1/admin/allow_new 存在
|
||
2. 默认是允许的（/v1/health 的 allowNew=True）
|
||
3. 关掉之后**新**设备注册被拒，且回 blocked=True
|
||
（客户端要靠这个标记区分"被管理员挡了"和"配对码冲突"）
|
||
4. 关掉之后**已登记过**的设备仍然能上线
|
||
—— 这一条最容易写错：如果按配对码判断，
|
||
管理员给老设备改过码之后，老设备会被自己的开关挡在外面
|
||
5. 重新打开之后新设备又能注册
|
||
6. 开关状态要能持久化（重启不丢）
|
||
|
||
B. 修改设备的配对码
|
||
1. 接口 /v1/admin/set_code 存在
|
||
2. 合法新码 -> 成功，且立刻生效
|
||
3. 旧码的映射被清掉（不能留成孤儿占位）
|
||
4. 已被别的设备占用 -> 拒
|
||
5. 非 6 位数字 -> 拒
|
||
6. 改成同一个码 -> 成功但 unchanged
|
||
7. 改码会踢掉该设备当前的会话
|
||
|
||
C. 管理页面上有对应控件
|
||
1. 有开关元素和文案
|
||
2. 每台设备有「改码」按钮
|
||
3. 「改码」按钮**不能**带 data-device ——
|
||
现有"单台删除"是按 button.danger[data-device] 绑的，
|
||
改码按钮要是也带上，点改码就会变成删设备
