Add localization support for game events, settings, and UI text elements (#1372)

## Description:

This PR adds missing translations for various UI components, including
game events and settings. No visual changes were made, so screenshots
are not required. All user-facing text has been properly localized and
added to the en.json file.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors

## Please put your Discord username so you can be contacted if a bug or
regression is found:
