feat(v1.7): 计数改已完成/总数、客户月历、套餐标签合并、批量开通、触控模式、按次到期

1) 日历计数口径
- 工作台与大屏的格子统一改为「已完成 / 总数」（如 2/5 = 共 5 单、做完 2 单）

2) 客户详情·当月排单
- 新增客户专属月历：每天显示 已完成/总数，可翻月，点某天跳转到日历对应日期
- 没有排单的日期淡化显示

3) 套餐标签与页签合并
- packages 新增 tag 列（可空），套餐编辑页可填
- 日历/大屏页签按标签合并：同标签套餐合成一个页签；勾了「独立显示」的套餐额外再开一个自己的页签
- 大屏同样支持标签筛选，链接参数为 tag=xxx

4) 批量开通
- 新增套餐详情页 /packages/{id}：显示套餐信息 + 客户列表
- 表头「全选」置顶，已订阅该套餐的客户置灰不可选；开始日期默认今天、天数/次数默认取套餐设置，均可改
- POST /packages/{id}/subscribe 批量开通，重复的自动跳过并汇总提示
- 修复 r.PostForm 未 ParseForm 导致拿不到勾选项的问题（批量打卡同源问题一并修正）

5) 触控 / PC 模式
- 尾号输入框右侧新增切换按钮，触控模式展开 3×4 键盘、输入框只读 + inputmode=none（不唤起系统输入法），按键直接写值
- 偏好记在 localStorage，默认 PC 模式（键盘收起）

6) 按次到期
- 按次订阅的到期日保持选填；填了到期后状态显示「已到期」且不再进日历待排（复用既有 end_date，无新列）

数据库兼容性：
- 只新增 packages.tag 一列，老库启动时自动 ALTER，可重复迁移；原有表结构与接口不变

测试：
- 无头 Chrome 实拍 5 张页面（日历/触控模式/客户月历/套餐批量/大屏）
- 功能验证 18 项全过（计数口径、标签页签、标签筛选、批量开通与重复跳过、月历翻月、触控开关、按次过期不上日历）
- 119 项验收回归全绿；go vet / go test ./... 通过；版本号 1.7.0
