feat(118): fakturownia single instance

Phase 118 complete:
- migration 20260512_000109 adds single global Fakturownia settings row
- FakturowniaIntegrationRepository simplified to one-instance API
- FakturowniaIntegrationController + edit view collapsed to one settings page
- Integrations hub shows Fakturownia as single instance
- Invoice config delegated flow always uses global integration_id

Note: shared routes/web.php and DOCS/* updates from Phase 118 are bundled
into the follow-up feat(121+122) commit because Phase 121/122 modified the
same files; hunk-level split was not performed.

+<objective>
+## Goal
+Convert Fakturownia from a multi-account integration to one global integration instance, like HostedSMS/SMSPLANET.
+
+## Purpose
+The operator should configure Fakturownia once. Invoice configs may still delegate invoice issuing to Fakturownia, but they must all point to the single global Fakturownia integration row.
+
+## Output
+One migration, one single-instance repository/controller/UI flow, updated invoice config handling, and updated technical documentation.
+</objective>

+<context>
+<clarifications>
+- **Migracja** - Co zrobic z istniejacymi wieloma kontami Fakturowni, jesli sa juz w bazie?
+  -> Odpowiedz: Wybrac aktywne konto.
+- **Kontrakty** - Czy delegowane konfiguracje faktur maja nadal trzymac `integration_id`, ale zawsze wskazywac jedyna globalna Fakturownie?
+  -> Odpowiedz: Tak.
+- **UI** - Jak ma wygladac UI Fakturowni?
+  -> Odpowiedz: Jedna strona z formularzem konfiguracji i testem polaczenia, bez dodawania wielu instancji.

+## Required Skills
+
+No blocking skills before APPLY.
+
+Project SPECIAL-FLOWS requires `sonar-scanner` after APPLY and before UNIFY when available in PATH.
+</skills>
+
+<acceptance_criteria>
+
+## AC-1: Jedna globalna konfiguracja Fakturowni
+```gherkin
+Given the operator opens /settings/integrations/fakturownia
+When the page renders
+Then there is one settings form with save and test actions, and no UI for adding, listing, or deleting multiple Fakturownia accounts
+```
+
+## AC-2: Migracja wybiera aktywna instancje
+```gherkin
+Given multiple integrations with type "fakturownia" exist before migration
+When the migration runs
+Then the active integration is preserved as the single global row, invoice_configs.integration_id values are reassigned to it, settings are preserved for that row, and extra unused Fakturownia rows are removed or detached safely
+```
+
+## AC-3: Delegacja faktur pozostaje kompatybilna
+```gherkin
+Given an invoice config has is_delegated = 1
+When it is saved or used to issue an invoice
+Then it points to the single global Fakturownia integration_id and InvoiceService can still call Fakturownia without schema changes
+```
+
+## AC-4: Hub integracji pokazuje pojedynczy status
+```gherkin
+Given the integrations hub is opened
+When Fakturownia row is displayed
+Then it shows one provider row with configured/active/token/test status for the global instance, not a count of instances
+```
+
+## AC-5: Dokumentacja jest aktualna
+```gherkin
+Given the implementation is complete
+When DOCS are reviewed
+Then DB_SCHEMA, ARCHITECTURE, and TECH_CHANGELOG describe Fakturownia as a fixed single-instance integration and note the migration behavior
+```

+  <action>
+    Create an idempotent migration that enforces the single-instance Fakturownia model without dropping existing invoice history.
+    - Pick the preserved row by priority: active Fakturownia integration first, then the one referenced by invoice_configs, then the lowest id.
+    - Ensure a base integrations row exists with type=fakturownia and name=Fakturownia if none exists.
+    - Ensure one fakturownia_integration_settings row exists for the preserved integration.
+    - Reassign invoice_configs.integration_id for delegated configs to the preserved integration.
+    - Remove extra fakturownia_integration_settings/integrations rows only after reassignment, using prepared migration SQL and FK-safe order.
+    - Add/adjust constraints so settings are fixed to id=1 when feasible without breaking MySQL compatibility.
+    Avoid: deleting invoices, changing invoices.config_id, or removing the invoice_configs.integration_id column.

+## DO NOT CHANGE
+- Do not remove `invoice_configs.integration_id`.

+- Do not add `invoice.created` automation event.
+- Do not implement Fakturownia double-POST idempotency in this plan.
+- Do not change HostedSMS/SMSPLANET behavior.
+
+## SCOPE LIMITS
+- This plan only changes Fakturownia account configuration from multi-instance to single-instance.
+- Existing delegated invoice issuing remains functionally the same after it resolves the global account.
+- Live Fakturownia API testing depends on operator credentials and network access.

+# Phase 118 Plan 01 Summary - Fakturownia Single Instance
+
+## Status
+
+APPLY complete on 2026-05-12 13:47. Ready for UNIFY.
+
+## Implemented
+
+- Added `database/migrations/20260512_000109_fakturownia_single_instance.sql`.
+- Converted `FakturowniaIntegrationRepository` to one global settings row with `getSettings()`, `saveSettings()`, `getIntegrationId()`, `getCredentials()`, and compatibility wrappers.
+- Simplified `FakturowniaIntegrationController` to one settings page plus save/test actions.
+- Replaced Fakturownia multi-account list UI with a single configuration form and test panel.
+- Updated integrations hub to show Fakturownia as one instance.
+- Updated delegated invoice config save flow to always use the global Fakturownia `integration_id`.
+- Removed the invoice config account selector and replaced it with global Fakturownia status.
+- Updated `DOCS/DB_SCHEMA.md`, `DOCS/ARCHITECTURE.md`, and `DOCS/TECH_CHANGELOG.md`.
+- Updated `.paul/codebase/db_schema.md`, `.paul/codebase/architecture.md`, and `.paul/codebase/tech_changelog.md`.
+
+## Verification
+
+- PASS: `C:\xampp\php\php.exe -l` for changed PHP classes and `routes/web.php`.
+- PASS: `C:\xampp\php\php.exe -l` for changed PHP views.
+- PASS: static search found no active UI links for adding/deleting Fakturownia accounts; legacy `/new` and `/edit` routes redirect to the global settings page.
+- BLOCKED: `C:\xampp\php\php.exe bin\migrate.php` could not connect to local MySQL (`SQLSTATE[HY000] [2002]` target actively refused connection).
+- SKIPPED: PHPUnit is not available in `vendor/bin`.
+- SKIPPED: `sonar-scanner` is not available in PATH.
+
+## Environment Gaps
+
+- Run `C:\xampp\php\php.exe bin\migrate.php` after local MySQL/XAMPP is running.
+- Manually verify `/settings/integrations`, `/settings/integrations/fakturownia`, save/test Fakturownia settings, and local/delegated invoice config edit.
+- Live Fakturownia API test still requires valid credentials and network access.
