fix: Reduce frequency of identity search requests in frontend

Thanks for submitting a PR! Please check the boxes below:

• I have filled in the "How did you test this code" section below?
• I have used a Conventional Commit title for this Pull Request

Changes:
This PR addresses issue #5370 where the frontend was making too many aggressive API requests to the identities endpoint when searching. I've implemented the following changes:

-->Increased the throttle delay in useSearchThrottle.ts from 100ms to 500ms
-->Increased the default throttle value in useInfiniteScroll.ts from 100ms to 500ms
-->These changes significantly reduce the request rate from the frontend while maintaining reasonable responsiveness. The throttling mechanism now waits longer between keystrokes before sending requests, preventing unnecessary database load.

Thanks for the contribution! It's working really well.

While I was comparing with using debounce. I realized the custom implementation we have of useThrottle in useSearchThrottle is actually more of a debounce one.

I'm approving as of because it's great but if ever in bonus you feel like renaming useThrottle into useDebounce and useSearchThrottle into useDebouncedSearch that'd be awesome

[Keerthi421]

@Zaimwa9 Sure , I will change

[Keerthi421]

@Zaimwa9 , I have made changes please review it

[Zaimwa9]

Thanks for the change.

One last thing to do and we are good to go:

• ~10 components are using the useSearchThrottle, replace it with your new useDebouncedSearch
• Remove the useSearchThrottle.ts file

And that should be good

Thanks again. One last back and forth as it doesn't build as of.

There is a import useThrottle from 'common/useThrottle' in TableSearchFilter that needs to be directly replaced with import useDebounce from 'common/useDebounce'
line 14 const searchItems = useDebounce(

Then we can approve
