[feat][experimental] Add auto-translate input message functionality and language support in chat panel and settings

This commit adds new entries in the language files and UI support for auto-translate messages.

The new feature uses a textarea input field to translate messages as they are typed, and the translated text is shown in a new field. Also, the language settings now provide an option to enable/disable auto message translation.

The code changes include adding a new function to update the input sizes for both input fields and some minor code refactoring to support new functionality.
