feat(admin): 余额脚本驱动的余额/配额刷新与管理端体验修复

- 明确刷新语义：仅脚本启用且已配置时触发远程查询；未配置时前端禁用并提示\n- 新增余额脚本安全开关 BALANCE_SCRIPT_ENABLED（默认开启），脚本测试接口受控\n- Redis 增加单账户脚本配置存取，响应透出 scriptEnabled/scriptConfigured 供 UI 判定\n- accountBalanceService：本地统计汇总改用 SCAN+pipeline，避免 KEYS；仅缓存远程成功结果，避免失败/降级覆盖有效缓存\n- 管理端体验：刷新按钮按配置状态灰置；脚本弹窗内容可滚动、底部操作栏固定，并 append-to-body 使弹窗跟随当前视窗
