Add Traditional Chinese Support and Fix JSON Format Errors

This pull request addresses two main changes:

1. **Add Traditional Chinese Support**: To make our application more accessible to a wider range of users, I have added support for Traditional Chinese (zh_TW). This includes the translation of all existing language keys into Traditional Chinese.

2. **Fix JSON Format Errors**: I've noticed that there were some issues with the JSON format in our language files. This included non-unique keys and missing translations. These issues have been addressed in this PR to improve the integrity of our data and avoid any potential issues in the future.
