   ## What is the purpose of the change
   
   #281 #274 #285
   
   ## Brief changelog
   
   The existing code for querying topics and consumers in the old version has a lot of redundant operations and repeated queries, which can easily lead to timeouts and errors when dealing with large data volumes. This PR mainly optimizes the speed of querying topics and consumers. Additionally, due to the longer time required to query consumers, caching is used to optimize the speed of the second query, and an option to refresh individual entries is provided. It also resolves the issue of confusion between delay topics and dead-letter topics.
