perf: avoid per-row Warehouse doc fetches in auto reorder job

Browse Source 
get_item_warehouse_projected_qty ran an uncached frappe.get_doc per Bin
row to walk the warehouse parent chain, re-fetching the same ancestors
for every item sharing a warehouse. Preload the warehouse parent map
once and walk it in memory instead.

(cherry picked from commit 6beb3d2509)
