fix(v1.8.1): 按次显示已完成/总次数、隐藏已开通套餐、已结束订阅置灰置底

1) 按次计费显示口径
- 订阅卡片、列表、大屏 TOP 都从「剩 x / y 次」改为「已完成 x / y 次」
- 进度条改为按已用次数计算

2) 开通订阅下拉过滤
- 客户详情「开通订阅」下拉自动隐藏该客户已开通的套餐，延期只能走「追加」入口，避免新开叠加
- 若客户已开通全部套餐，下拉只剩占位项

3) 已结束订阅置灰置底
- 客户详情的订阅卡片按「进行中 → 已结束」排序，已结束排到最后
- 已结束卡片降低透明度、降低饱和度，鼠标悬停恢复部分可见

数据库：无变更
测试：
- 功能验证 5 项：按次文案、已开通套餐不在下拉、未开通仍可选、已结束卡片置灰、已结束排在最后
- 119 项验收回归全绿（8 条按次断言随之更新为新口径）
- 无头 Chrome 实拍客户详情页；版本号 1.8.1
