feat: 考勤打卡模块（NFC）重新开发

基于新方法论（11层源码分析+独立评审）重新开发考勤打卡功能：
- 首页下拉展开打卡面板，点击按钮开启NFC贴卡打卡
- 支持上班打卡、下班打卡、撤销打卡
- NFC超时自动关闭，音效反馈（4种planId）
- MQTT type=5 上下班状态推送处理
- 按钮状态矩阵：onPunchState×offPunchState决定显示

新增: AttendanceStatus / PunchApi / PunchViewModel / PunchPanelView
修改: NetworkModule / HomeFragment / fragment_home.xml
删除: AttendanceInfo（被AttendanceStatus替代）
