feat(resource-status): enrich LOT tooltip with product/material info and draggable header

Add WIP detail API integration to FloatingTooltip for LOT popups, displaying
product info (Product, Product Line, Package, Workorder) and material info
(Wafer Lot ID, Wafer P/N, Leadframe, Compound) with client-side caching.
Make the tooltip header draggable for both LOT and JOB popups.
