Refactor approval buttons into reusable component

Extract LoadingSpinner and ApprovalActionButtons components and replace duplicated approve/search/deny button blocks with the new ApprovalActionButtons to reduce duplication and centralize behavior/styles. Remove the inline LoadingSpinner in PendingApprovalSection, add an aria-label to the details button, and update the details modal's adminActions to use ApprovalActionButtons with callbacks that handle approval/denial/search and close modals as needed. Improves DRY, maintainability, and consistency of loading state handling.
