Close purchase orders, and drill into the procurement numbers

The procurement home's top-line tiles were read-only — you could see $480k committed but not which POs made up the number. Now every tile is a drill-down: click Committed, Open, Received, or Draft and the list below filters to exactly those POs (click again to get the full list back). Received and Draft show their dollar totals too, so the whole cashflow picture — committed, still undelivered, delivered, and not-yet-committed — reads straight off the four tiles.

And the lifecycle finally has an ending. Receiving already walked a PO from Issued to Partially Received to Received on its own, but nothing came after. There's now a Close PO action on any issued PO: once you expect no further receipts or charges against it, close it and it locks for good — no more edits, no charge toggles, and your Open number stays honest. Closed POs still count in Committed and Received history.

Also fixed: product descriptions on PO lines were getting clipped in the narrow column — the page is wider, the description column has room, and hovering any description shows the full text.
