Gives the operator two new controls on a collection-pool stop, and fixes
the audit feed they write into.
Back-to-pending (`items/[id]/back-to-pending`)
A stop has to come back when the driver can't take it — no-show,
wrong date, supplier pushed the delivery — or when the supplier
confirmation was premature. A row can be assigned to a driver and/or
marked ready at the same time, so the route clears both in one write
rather than making the operator unwind them in the wrong order.
Collection date (`items/[id]/collection-date`)
`order_items.collection_date` was a PB date field that existed but
nothing read or wrote it. On a PENDING stop it is a forecast — the
supplier said goods land on the 20th, so the stop stays
un-assignable because promising a driver a pickup for goods that
don't exist yet would be a lie. On a READY stop it is the confirmed
collection day.
Notes feed (`src/lib/note-feed.ts`)
`notes` on order_items / stock_purchase_items is NOT free text — it
is a JSON array of NoteEntry objects, and every consumer parses it as
one. The assign route's "mark ready" path wrote a plain string into
it, which silently destroys the entire history: the next parse falls
back to an empty feed. All writers now go through `appendNote` with
the row's current value. Lives in `src/lib` rather than a page view
model because both the client pages and the server routes need it,
and an API route must never import from `app/(app)`.
