Fix context menu import causing movies not to load

- Fix incorrect import: change 'from . import translation' to
  'from .utils import translate_string'
- Add try/except block to prevent context menu errors from breaking playback
- Add defensive check for item_details.id existence
- Add error logging for debugging context menu issues

This fixes the critical bug where the movie menu would not load
due to the incorrect translation import.
