feat(115): wystawianie faktury z zamowienia (lokalne + delegowane Fakturownia)

Phase 115 complete (vertical slice "zamowienie z NIP -> faktura PDF"):
- Task 1: InvoiceRepository + InvoiceService (dual-flow orchestrator) +
  InvoiceIssueException + FakturowniaApiClient::createInvoice + buildPdfUrl
- Task 2: InvoiceController + OrdersController::toggleInvoiceRequested +
  OrdersRepository::setInvoiceRequested + auto-import invoice_requested z
  Allegro (invoice.required) i shopPRO (5-key flexible parser) + show.php
  (toggle w zakladce Platnosci + warunkowy przycisk Wystaw fakture)
- Task 3: Lista wystawionych /settings/accounting/invoices/issued z filtrami
  + invoice_preview + invoice_pdf Dompdf template + hub link
- Task 3b (dodany): NIP lookup przez MF Biala Lista (publiczne API, bez
  rejestracji) — MfWhitelistApiClient w src/Core/Http/ + /api/nip/lookup +
  przycisk "Pobierz z GUS" w formularzu

Auto-fixes podczas smoke testu (5):
- GUS endpoint Fakturowni nie istnial (HTML 404 -> "json is not valid");
  switch na MF Biala Liste
- PHP 8.5 curl_close() deprecation wycieka HTML przed JSON; usuniete z
  MfWhitelistApiClient i FakturowniaApiClient (3 miejsca)
- Fakturownia 422 payment_to_kind_days (nieistniejace pole) -> usuniete
- Generic "error" w 422 -> parser plaskuje errors: {pole: [...]} +
  error_log z 1000 znakow raw body
- Fakturownia security odrzuca seller_*/department_id jako "create new
  department"; usuniete z payloadu (Fakturownia uzywa danych konta)
