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)

+## Phase 115 — Wystawianie faktury z zamowienia
+
+### InvoiceService (`src/Modules/Accounting/InvoiceService.php`)
+- `issue(array $params): array` — orchestrator. Walidacja config (active), order details fetch, build snapshots (seller z `company_settings`, buyer merged z payload_json+addresses+manual override, items z VAT-aware netto/brutto split), routing do `issueLocal()` lub `issueDelegated()` zaleznie od `invoice_configs.is_delegated`.
+- `issueLocal()` — `InvoiceRepository::nextLocalNumber()` (atomowy counter z `invoice_number_counters`) -> `insertLocal()` -> zwraca `{invoice_id, invoice_number, total_gross, mode='local'}`.
+- `issueDelegated()` — `FakturowniaApiClient::createInvoice()` PRZED INSERT lokalnym; on success zapis `external_invoice_id`/`external_pdf_url`/`invoice_number` z odpowiedzi API; on failure rzuca `InvoiceIssueException` (zaden wiersz w `invoices`). `invoice_number_counters` NIE jest dotykany dla delegated.
+- Static `extractBuyerTaxNumber($order, $buyerAddress)` — parsuje NIP z payload_json sciezki: `invoice.address.taxId` (Allegro), `invoice.taxId/nip`, `buyer.tax_number/nip`, `client.nip/tax_number`, top-level `nip/tax_number`. Fallback na `order_addresses.company_tax_number`.
+
+### InvoiceRepository (`src/Modules/Accounting/InvoiceRepository.php`)
+- `findByOrderId/findById` — JOIN `invoices` + `invoice_configs` + `integrations` (type='fakturownia') + `fakturownia_integration_settings` (LEFT JOIN dla `account_prefix`).
+- `insertLocal/insertDelegated` — wspolny prywatny `insert()` z roznymi NULL-amizacjami `external_*` pol.
+- `nextLocalNumber()` — `INSERT ... ON DUPLICATE KEY UPDATE last_number = last_number + 1` na `invoice_number_counters`, mirror `ReceiptRepository::getNextNumber`.
+- `paginate()` — filtry: `search` (numer/order ref), `config_id`, `mode` (local/delegated rozroznia po `external_invoice_id IS NULL`), `date_from`/`date_to`.
+
+### FakturowniaApiClient (rozszerzony)
+- `createInvoice(array $settings, array $invoice)` — POST `https://{prefix}.fakturownia.pl/invoices.json` z body `{api_token, invoice}`. cURL z `SslCertificateResolver`, timeout `$timeoutSeconds`. On 2xx parsuje JSON na `{id, number, view_url, pdf_url, raw}`. On non-2xx rzuca `RuntimeException("HTTP {code}: {error}")`.
+- `buildPdfUrl(prefix, invoiceId, apiToken)` — string-builder dla `https://{prefix}.fakturownia.pl/invoices/{id}.pdf?api_token=...`. Bez fetcha; uzywany w redirect 302.
+- Dodany `httpPostJson()` (private) odpowiednik istniejacego `httpGet()`.
+
+### InvoiceController (`src/Modules/Accounting/InvoiceController.php`)
+- `create(Request)` — GET `/orders/{id}/invoice/create`. Walidacja `orders.invoice_requested=1` (przekierowanie z flash error gdy 0). Active configs (filter `is_active=1`). NIP auto-prefill via `InvoiceService::extractBuyerTaxNumber()`. Renderuje `accounting/invoice_form`.
+- `store(Request)` — POST `/orders/{id}/invoice/store`. CSRF, `config_id` walidacja. Wywoluje `InvoiceService::issue()` z buyer overrides z formularza. On success: `OrdersRepository::recordActivity('invoice_issued')`, flash success, redirect na `/orders/{id}/invoice/{invoiceId}`. On `InvoiceIssueException`: flash do `invoice.error`, redirect z powrotem na form.
+- `show(Request)` — GET `/orders/{id}/invoice/{invoiceId}`. HTML preview z snapshotow.
+- `pdf(Request)` — GET `/orders/{id}/invoice/{invoiceId}/pdf`. Gdy `external_pdf_url` istnieje -> redirect 302; inaczej Dompdf inline z templatu `accounting/invoice_pdf`.
+- `issuedList(Request)` — GET `/settings/accounting/invoices/issued`. Filtry GET, paginacja 50/strona.
+
+### orders.invoice_requested toggle
+- `OrdersRepository::setInvoiceRequested(int, bool)` — UPDATE z `updated_at = NOW()`.
+- `OrdersController::toggleInvoiceRequested` — POST `/orders/{id}/invoice-requested/toggle`. CSRF, JSON response `{success, invoice_requested}`. Loguje `order_activity_log` z `event_type='invoice_requested_changed'`.
+- `public/assets/js/modules/invoice-requested-toggle.js` — vanilla JS, idempotent guard `dataset.bound='1'`. AJAX POST przy `change`, optimistic show/hide `[data-invoice-button-wrap]`. Rollback checkbox przy HTTP/network blad.
+
+### Auto-import flagi invoice_requested
+- `AllegroOrderImportService::importSingleOrder` — przy `wasCreated=true` jezeli `payload.invoice.required` truthy -> `setInvoiceRequested(true)`. Tylko pierwszy import (delta-only re-import nie nadpisuje manualnej zmiany).
+- `ShopproOrdersSyncService::shouldRequestInvoice($rawOrder)` — flexible parser sprawdzajacy `wants_invoice`, `invoice_required`, `invoice.required`, `buyer.wants_invoice`, `buyer.invoice` (akceptuje true/1/'1'/'true'/'yes'/'tak'). Wywolany tylko przy `wasCreated=true`.
+
+### View hierarchy
+- `accounting/invoice_form.php` — formularz wystawiania.
+- `accounting/invoice_preview.php` — HTML preview po wystawieniu.
+- `accounting/invoice_pdf.php` — template Dompdf, mirror `receipts/print.php` z dodatkowymi polami faktury VAT (parties, netto/VAT/brutto per stawka, termin platnosci).
+- `accounting/invoices_issued_list.php` — lista pod `/settings/accounting/invoices/issued`.
+- `orders/show.php` — checkbox toggle + warunkowy przycisk "Wystaw fakture" + sekcja "Faktury" w tabie documents.
+
+### DI wiring (`routes/web.php`)
+- `$invoiceRepository = new InvoiceRepository($app->db());` (po `InvoiceConfigRepository`).
+- `$invoiceService = new InvoiceService($invoiceRepository, $invoiceConfigRepository, $companySettingsRepository, new OrdersRepository(...), $fakturowniaIntegrationRepository, $fakturowniaApiClient);`
+- `$invoiceController = new InvoiceController($template, $translator, $auth, $invoiceRepository, $invoiceConfigRepository, $companySettingsRepository, new OrdersRepository(...), $invoiceService);`
+- `$ordersController` rozszerzony o 2 trailing params: `$invoiceRepository`, `$invoiceConfigRepository`.
+
+### BREAKING / migration
+- Zadnych nowych migracji — Phase 113-01 dostarczyla `orders.invoice_requested`, `invoice_configs/invoices/invoice_number_counters` i `fakturownia_integration_settings`.
+- `OrdersController` ctor dostal 2 NEW optional params (default null) — backwards compatible.
+
+### Edge cases / known limits
+- INVOICE-IDEMP-115 (`.paul/codebase/todo.md`) — brak idempotencji przy double-POST do Fakturowni gdy odpowiedz nie dotrze; operator musi recznie zweryfikowac w panelu.
+- Brak `invoice.created` event automatyzacji (per Phase 113 decision).
+- Brak download+cache PDF z Fakturowni — tylko redirect 302 (kazdy klik na PDF dla delegated faktury fetchuje PDF z Fakturowni).
