[FIX] Add mutation subscription to catch mutations

[Rezrazi]

This pull request refactors and improves the synchronization logic between the query/mutation cache and the dashboard in the useSyncQueriesExternal hook. The main focus is to ensure that both query and mutation state changes are properly synced, and to make the sync logic more reusable and maintainable.

Synchronization improvements:

• Extracted the state synchronization logic to a reusable function called syncStateToDesktop, improving code clarity and maintainability.
• Subscribed to both the query cache and the mutation cache using queryClient.getQueryCache().subscribe(syncStateToDesktop) and queryClient.getMutationCache().subscribe(syncStateToDesktop), ensuring that all relevant state changes are propagated to the dashboard.

Cleanup and resource management:

• Updated the cleanup function to properly unsubscribe from both the query and mutation cache subscriptions by calling queryCacheSubscription() and mutationCacheSubscription().
