cyber_monitor bug

[DieYoungWsn]

cyber_monitor在第二层界面想查看repeated字段时（进入第三层界面），偶发性的coredump。 查看源码可知message_ptr_是用的刚进入第三层界面时的值，而channel_msg_ptr->raw_msg_class_是实时更新的，导致message_ptr是一个悬垂指针（message_ptr来源于raw_msg_class)。解决办法：要么舍弃实时更新repeated字段的值，要么就保存当前repeated的Protobuf 反射相关的信息，实时从raw_msg_class里面解析字段出来。

When attempting to view repeated fields in the third-level interface (after entering from the second-level), an intermittent core dump occurs.

Root Cause Analysis:
The message_ptr_ value captured upon entering the third-level interface becomes invalid when channel_msg_ptr->raw_msg_class_ is updated in real-time. This occurs because:

1. message_ptr_ is derived from raw_msg_class_
2. Real-time updates to raw_msg_class_ cause message_ptr_ to become a dangling pointer

Proposed Solutions:

1. Disable Real-time Updates for Repeated Fields. Stop live updates of repeated field values in the third-level interface
2. Persist Protobuf Reflection Metadata.Save the current repeated field's reflection information.Dynamically parse fields from raw_msg_class_ using preserved metadata
