i18n: fix german translation for OAUTH_PROVIDER_NAME

feat: Replace message event

- Corrected placeholder from {{Anbieter}} to {{provider}}

fix: preselect default model from config if no setting stored

Update translation.json

Word not necessary in Lithuanian so modified it to be an arrow which would look good design wise and would not be weird gramatically

refactor: Refactor backend/main.py
