feat(webshop): generate orderunderlag and attach it to the verifikat at booking (#1899)

* feat(webshop): generate orderunderlag PDF and attach it to the verifikat at booking

Booked webshop orders only carried the VAT split; the verifikat showed no
product lines, customer or payment method although the sync already stores
all of it in webshop_orders.line_items (#1881).

- lib/webshop-orders/order-underlag.tsx: pure model builder + react-pdf
  template (order lines, customer, payment method, per-rate VAT summary,
  SEK conversion facts) + archiveWebshopOrderUnderlag, which renders and
  archives the PDF on the committed verifikat through uploadDocument
  (upload_source system, extraction none), mirroring archiveIssuedInvoicePdf.
  Never throws: the booking is immutable by then.
- book route: archive after commitEntry; response gains underlag_archived.
  FX-retry now also syncs the in-memory row so the underlag shows the
  resolved SEK facts.
- webshop_order added to NEEDS_DOC_SOURCE_TYPES and (new migration
  20260825140000) to the verifikat_without_documents needs-doc list, so a
  failed attach or a historical booking surfaces on the saknar-underlag
  worklist. transactions_without_documents is deliberately unchanged.
- tests: underlag model/render/archive unit tests, book-route archive and
  failure-isolation cases, pg test extended (per-source-type probe now
  covers webshop_order; explicit flagged/silenced pair).

Fixes #1881

* fix(webshop): skeptic findings on the orderunderlag (#1881)

Two refutations from the skeptic pass on PR #1899, both fixed:

1. Correctness: sv-SE Intl emits U+2212 MINUS SIGN for negatives, which
   Helvetica/WinAnsi PDF fonts drop silently, so refund and discount
   amounts on the archived underlag rendered as POSITIVE. formatAmount now
   replaces U+2212 with an ASCII hyphen (same guard as formatPdfCurrency),
   is exported, and is pinned by a regression test.

2. Regression: NEEDS_DOC_SOURCE_TYPES had two hardcoded copies that missed
   webshop_order, so flagged rows rendered without the "Underlag saknas"
   chip, waiver toggle, or batch-exempt selection, and the weekly
   missing-underlag push cron disagreed with the badge. The constant now
   lives in dependency-free lib/worklist/types.ts (client-safe), is
   re-exported from categories.ts, and both JournalEntryList.tsx and
   push-notifications/notification-scheduler.ts consume it instead of
   their own copies.

Also: "Bokfört i SEK" reworded to "Motsvarande i SEK" (compliance skeptic
observation: the dialog's lines are user-editable, so the underlag must
state the order's conversion, not claim a booking fact).
