fix(po): upload attachments server-side so they persist & show
PO/receipt attachments were uploaded via a browser presigned PUT straight
to R2 (POST /api/files/sign -> PUT uploadUrl -> linkDocument). That direct
browser->R2 PUT only succeeds when the bucket carries a CORS policy
allowing PUT from the portal origin; in production that policy was missing,
so the browser silently blocked the PUT, linkDocument never ran, and no
PODocument row was created -- "documents uploaded but not visible anywhere"
(0 PODocument rows in prod/staging).

Route uploads through a server action (uploadPoDocuments) that writes the
file with uploadBuffer and creates the PODocument row atomically -- the
same pattern the crewing module already uses for CV/crew-document uploads,
and within the 10mb serverActions.bodySizeLimit. This removes the R2-CORS
dependency and guarantees a created row always has its stored file.

Removes the now-dead presigned path (lib/upload-files.ts,
app/actions/link-document.ts, api/files/sign/route.ts).

Adds an integration test that drives the action against a real DB and
asserts the PODocument row is created and surfaced by the exact include
the PO detail page renders from (i.e. the attachment is visible).

* Replaces the earlier browser-presigned-PUT flow (`POST /api/files/sign` → the
* browser `PUT`s the file straight to R2 → `linkDocument` creates the row). That
* direct browser→R2 `PUT` only works if the R2 bucket carries a CORS policy
* allowing `PUT` from the portal's origin. In production that policy was missing,
* so the browser silently blocked the upload, `linkDocument` was never reached,

* visible anywhere" report (0 PODocument rows in prod/staging).
*
* Uploading through the server — the same pattern the crewing module already uses
* for CVs / crew documents (`uploadBuffer`) — removes the CORS dependency and
* makes the store-and-link atomic, so a created row always has its file.
*
* Returns `{ error }` on the first failure, or `null` on success (the contract
* the PO and receipt forms already expect).
