Complete the Japanese (日本語) translation of Puter

[jelveh]

The Japanese version of Puter is missing a number of translations. This task involves updating the Japanese translation file to ensure that all English text is accurately translated and culturally appropriate.

Steps to resolve

1. Scroll to the bottom of src/gui/src/i18n/translations/ja.js to find the list of missing translations
2. For each translation key that is missing the value is left as undefined, however the English translation is provided in the comment next to it.
3. Replace undefined with the Japanese translation of the English text provided in the comment

Additional notes

• Please pick up this task only if you're fluent in Japanese. This is to make sure the nuances of the language are observed accurately.
• Please ensure that the translations are culturally appropriate and maintain the intended meaning of the English text
• If certain terms or phrases don't have a direct Japanese equivalent, consider adding translator notes or using transliteration where appropriate
• Please be mindful of placeholders such as %strong% and try to appropriately place them in the translated text
