feat(summary): add auto-summary preference for message previews

- Add new preference option to enable automatic AI summarization
- Update all localization files with new preference text
- Implement preference check in message display script
- Add default preference setting in options configuration
- Include preference toggle in options UI

This adds a user-configurable option to automatically generate and display AI summaries when viewing email messages, with appropriate warnings about data transmission to AI services.
