feat(procurement): validate acquisition lease fields and enforce bulk-receive capacity

Reject lease start/end and monthly payment on PURCHASE acquisitions (create and
update, validated against the resulting record). Add asset_acquisitions.item_name
column + migration. Enforce warehouse/yard/zone capacity on bulk receive and apply
capacity-counter deltas on save. Adds acquisition-guard spec.
