refactor(config): config dosyası bağımlılığını kaldır

Config dosyası (.game-bash.conf) desteğini kaldırıp sadece .env dosyası
kullanımına geçildi. IGDB token artık disk yerine RAM'de önbelleğleniyor
(oturum bazlı). Authentication işlemi taramadan önce gerçekleştiriliyor.

Değişiklikler:
- config_load, config_save, config_get, config_set fonksiyonları kaldırıldı
- Token süre kontrolü ve disk önbellekleme sistemi kaldırıldı
- --config ve --init CLI seçenekleri kaldırıldı
- scanner_clear_test_posters fonksiyonu eklendi
- Test modunda poster temizleme önceden yapılıyor
- Hata mesajları .env dosyasına yönlendirildi

BREAKING CHANGE: Config dosyası desteği tamamen kaldırıldı. Artık sadece
.env dosyası ile yapılandırma yapılabilir. Kullanıcıların .env dosyası
oluşturması gerekmektedir.
