Fix: testy + bugfix SettingsRepository::allSettings() + migracja phpunit.xml

- SettingsRepository::allSettings() — inicjalizacja $settings = [] przed pętlą
  (bug: false ?? [] zwracało false gdy cache pusty a DB null)
- Stuby wydzielone do tests/stubs/CacheHandler.php + S.php
- phpunit.xml zmigurowany do schematu PHPUnit 10 (coverage → source)
- composer.lock dodany do repozytorium
