The approving Manager decides how much of the PO is paid first, via a
0–100% slider on the approval card (default 100% = full). The slider is
convenience only — the resolved ABSOLUTE amount is stored on
PurchaseOrder.suggestedAdvancePayment (Decimal(12,2), nullable).
- schema + migration: add suggestedAdvancePayment (null = no explicit
advance ⇒ full payment, preserves legacy behaviour).
- approvePo(): accepts the amount, clamps to [0, totalAmount], persists
it, records it on the APPROVED audit row. Set once at approval; never
edited afterwards.
- approval-actions.tsx: whole-percent slider showing the resolved ₹
amount + remaining balance; value sent with Approve / Approve-with-Remarks.
- Accounts surface: payment queue + PO detail show the advance; it
prefills the FIRST payment amount (only when nothing is paid yet and
it is a true partial). Balance runs the normal PARTIALLY_PAID loop.
- Not shown on the exported PO/invoice (po-export-layout untouched).
- Tests: persist + audit metadata + clamp-to-total.
