Update Japanese translation .po file.

Added translations to untranslated parts in the ja.po file.
- Focused on significant edits to the settings window and the "Calibration" tab.
- Aligned the terminology for the build plate, including the newly added "SuperTack," with the official store's naming conventions.
- Corrected unnatural phrasing in Japanese and standardized terms for consistency.

I'm not very experienced, so I apologize if there are any mistakes. Please feel free to provide correction instructions.
Thank you!
