debug(android): 添加崩溃日志和调试信息定位待机闪退问题

- TssPartyApplication: 添加全局异常捕获，崩溃日志保存到文件
- GrpcClient: 心跳失败、重连、流重订阅添加 [IDLE_CRASH_DEBUG] 日志
- TssRepository: 轮询超时和回调调用添加调试日志
- MainViewModel: session事件回调用try-catch包装

日志筛选: adb logcat | grep "IDLE_CRASH_DEBUG"
崩溃日志: /data/data/com.durian.tssparty/files/crash_logs/
