A hidden, installable PWA: one link, opened on a phone, showing where
every order is. New / Processing / Completed, with a tap-to-preview
popup and the invoice/line detail Gary needs. Read-only, and NOT in
the sidebar — the route lives outside `(app)`, so `<Sidebar />` never
renders there.
The preview popup is reused, not rebuilt: the service emits
`UniversalHit`s and the page hands them to the existing
`SearchPreviewDialog`, so the manager gets the desk's quick-overview
verbatim.
Also fixes the /orders Completed tab, which was matching ZERO orders.
`delivered_at` is stamped on only 2 of 12,957 delivered lines and the
business stopped writing `delivered` on 2026-08-14 (the live pipeline
now ends at `invoiced` / `checked_in`), so the old filter never
matched. "Settled" is now defined once — `SETTLED_STATUSES` +
`SETTLED_DATE_FIELDS` — and dated per status: `invoiced_date` for
invoiced (the only properly stamped field, 2,199 lines), `delivered_at`
for delivered, `updated` only where no dedicated column exists.
`delivery_note` and `checked_in` move into `completed` as instructed,
and the standalone `post_processing` tab is retired (a DN is not a
stage of its own). `invoiced` stays in `collected` as well, so
invoiced orders don't vanish from the workflow tabs.
Completed tab: 0 -> 341 orders over 30 days, 112 over 7.
