feat：单账户配置余额脚本 + 刷新按钮即用脚本”，并去掉独立页面/标签。

具体改动

  - 后端
      - src/models/redis.js：新增脚本配置存取 account_balance_script:{platform}:{accountId}。
      - src/services/accountBalanceService.js：支持脚本查询。若账户有脚本配置且 queryApi=true，调用 balanceScriptService.execute 获取余额/配额，缓存后返回。
      - src/routes/admin/accountBalance.js：新增接口
          - GET /admin/accounts/:id/balance/script?platform=...
          - PUT /admin/accounts/:id/balance/script?platform=...
          - POST /admin/accounts/:id/balance/script/test?platform=...
  - 前端
      - 新增弹窗 AccountBalanceScriptModal，在账户管理页每个账户“余额/配额”下方有“配置余额脚本”按钮，支持填写 baseUrl/apiKey/token/extra/超时/自动间隔、编写脚本、测试、保存。
      - 将余额脚本独立路由/标签移除。
  - 格式/ lint 已通过（新组件及 AccountsView）。
