feat(125): invoice_requested import fix + drop legacy is_invoice column

- shopPRO: ShopproOrderMapper jako jedyne zrodlo heurystyki detekcji faktury;
  mapOrderAggregate() zwraca top-level invoice_detected (transient).
- ShopproOrdersSyncService: usunieta wlasna shouldRequestInvoice(); propagacja
  aggregate['invoice_detected'] do setInvoiceRequested() tylko przy created=true.
- Allegro: nowa shouldRequestInvoice(payload) z 4 wzorcami (invoice.required,
  naturalPerson=false, address.taxId, companyName/address.company.name).
  Wczesniej tylko invoice.required -> analogiczna luka jak shopPRO.
- Migracja 20260513_000113: idempotentny backfill (UPDATE invoice_requested=1
  WHERE is_invoice=1 AND invoice_requested=0) + DROP COLUMN orders.is_invoice.
  Guard przez information_schema.COLUMNS + PREPARE/EXECUTE z ALTER TABLE COMMENT
  no-op fallbackiem (portable MySQL/MariaDB).
- Cleanup is_invoice z OrderImportRepository (INSERT cols/values/params,
  docstring Phase 112) i OrdersRepository (paginate SELECT, transformOrderRow
  hydrate). AllegroOrderImportService mapping w mapCheckoutFormPayload tez
  usuniety (wymuszone konsekwencja DROP COLUMN).
- Bugfix #1089: zamowienie shopPRO z firm_nip (bez wants_invoice/invoice.required)
  ustawia teraz invoice_requested=1 -> UI w zakladce Platnosci zaznacza checkbox,
  przycisk "Wystaw fakture" widoczny.

Pending operator: php bin/migrate.php (XAMPP MySQL online) -> backfill 7 zamowien.
Smoke test: re-import shopPRO + nowe Allegro z NIP.
