Firebase KTX import를 non-KTX로 마이그레이션

- Firebase.ktx.Firebase → Firebase.Firebase
- firestore.ktx.firestore → firestore.firestore
- remoteconfig.ktx.remoteConfig → remoteconfig.remoteConfig
- remoteconfig.ktx.remoteConfigSettings → remoteconfig.remoteConfigSettings
- 영향 파일: ServiceModule, MainActivity
- BOM 34.x 업그레이드 사전 준비 (34.x에서 -ktx 모듈 제거 예정)
