UIIN-3626: Item reorder changes are lost if holdings accordion is collapsed before 'stop item movement' invoked

[mariia-aloshyna]

Purpose

This PR prevents unnecessary item refetches when reopening Holdings accordions and preserves unsaved item reordering state across accordion collapse/expand in Instance details.

Approach

• Updated useHoldingItemsQuery caching strategy to reuse data for identical requests:
• query key now includes full searchParams (stable request identity)
• defaulted to staleTime: Infinity and refetchOnMount: false to avoid remount refetch for unchanged params
• Added test in useHoldingItemsQuery.test.js to verify no refetch occurs on unmount/remount with the same request.
• Updated HoldingAccordion rendering behavior:
• keep items content mounted after first open
• hide/show content on collapse/expand instead of unmounting
• This preserves local DnD/order-management state so unsaved reordered items do not reset when the accordion is toggled.
