翻訳バックエンドを拡張・リファクタリング：OpenAI/Plamo/Gemini クライアントを追加・改修し、プロンプトを YAML から読み込むように変更。各クライアントでモデル一覧取得・認証・クライアント更新機能を実装し、Translator/Model 層の対応メソッドを追加。Controller と mainloop にプラモ・ジェミニ・OpenAI の認証/モデル操作エンドポイントを追加・整備。config のモデル/API設定をプロパティ化して既定値を None に変更し、選択肢リストを初期化。translation_languages に OpenAI 用マッピングを追加。requirements ファイルの依存記述を調整。
