Currently, when loading chart template translations, existing translations
cannot be overwritten for records with noupdate=True flag, even when localization updates require translation corrections.

This limitation prevents proper localization maintenance, especially when:
- Chart template translations need to be updated to fix incorrect or outdated translations
- Localization modules need to ensure translations are synchronized with the latest chart template versions
- Manual translation corrections need to be applied during localization setup or updates

By adding the force_overwrite parameter, localization modules can now explicitly request to overwrite existing translations, including those protected by noupdate=True, enabling proper translation management for localization purposes.

The parameter defaults to False to maintain backward compatibility and preserve existing behavior when not explicitly requested.
