/**
|
||
* 账户配置的读取与保存。
|
||
*
|
||
* 位置优先级：
|
||
* 1. 环境变量 WPYWMAIL_ACCOUNT_FILE 指定的文件（自测/多账户时用）
|
||
* 2. %LOCALAPPDATA%\WpywMailClient\account.json（默认，跟着用户走）
|
||
*
|
||
* 安全说明（不粉饰）：密码以明文存在这个文件里。这是自研客户端的常见做法
|
||
* （Thunderbird 之类会用系统凭据库/主密码，那需要额外依赖）。本文件只放在
|
||
* 当前用户自己的 profile 目录下，不做任何网络传输；若在意，可把
|
||
* account.savePassword 设为 false，每次启动时手动输入密码。
