feat(i18n): add model name display option and improve localization, fixes #440

- Add new model name display setting with options to show model name or file name
- Implement helper function to determine display name based on user preference
- Update model card footer to use dynamic display name
- Include model name display setting in settings modal and state management
- Remove redundant labels from display density descriptions in multiple locales
- Simplify card info display descriptions by removing duplicate text

The changes provide cleaner UI text and add flexibility for users to choose between displaying model names or file names in card footers.
