feat(core): add default group and order (#12526)

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **New Features**
  - Added default sorting and grouping by "Last Updated" for document views.
  - Introduced clearer group headers for documents grouped by creation or update date, displaying relative dates or appropriate fallback text.

- **Improvements**
  - Enhanced date grouping headers with capitalized, user-friendly text and improved handling of missing dates.
  - Added a new localization for "Never updated" to improve clarity in document groupings.
  - Initialized document update timestamps at creation to improve date accuracy.
