Code Review

This pull request introduces a custom useDebouncedValue hook to optimize search functionality in the Pods and Queues components, reducing the frequency of API calls. While the implementation improves performance, the reviewer identified a regression in the handleRefresh logic where data may fail to reload if the search state remains unchanged. Additional feedback includes standardizing React state setter naming conventions and correcting minor syntax issues such as missing semicolons.
