Quotation and layaway endpoints were calling calculate_totals() on raw
input items without looking up unit_price/tax_rate from inventory, causing
KeyError. Added _enrich_items() helper (with customer price tier support).
Also removed non-existent discount_total column from quotations INSERT,
and made layaway complete accept a final payment for the remaining balance.
