Commit Summary 更新大綱

• Add new translations for strings that have not been translated yet. 對尚未翻譯的字串加入正體中文（臺灣）的翻譯。

1. “固定值” for Fixed
2. “主圖表縮放” for Main chart scaling
3. “縮放值” for Scale value

• Optimize localization quality: replace the term's translating of "threshold" from "臨界點" to "臨界值." 最佳化翻譯品質：將threshold的翻譯從「臨界點」變更為「臨界值」。
