[front] - feature: implement partial check state in permissions tree

 - Introduce lodash and memoization to determine parents with checked children in the permission tree
 - Modify the permission update logic to support partial checked states based on parent-child relationships
 - Utilize custom hooks to optimize fetching and mapping the required resources for permission states
