Refaktoryzacja struktury konfiguracji NixOS

- Usunięcie zbędnych parametrów wejściowych funkcji konfiguracyjnej
- Przeniesienie ustawień do oddzielnych plików w katalogu `config/`
- Uproszczenie struktury `config.nix` poprzez delegację ustawień do modułów
- Zachowanie wcześniejszych importów modułów sprzętowych
