## Summary by CodeRabbit
- **Refactor**
- Centralized state management in the document explorer using a reactive context, replacing prop drilling and local state with observable streams for preferences, selection, grouping, and view options.
- Updated multiple components (display menus, quick actions, doc list items, group headers) to consume and update state directly via context observables.
- Simplified component signatures by removing now-unnecessary props related to preferences and state handlers.
- **Style**
- Adjusted user avatar display: avatars now only have right margin when user names are shown, and vertical alignment was improved.
- **New Features**
- User avatar elements now include a data attribute to indicate if the user name is displayed.
- **Bug Fixes**
- Improved handling of document tags to prevent errors when tags are not in the expected format.
- **Documentation**
- Added missing group header property for updated date fields in workspace property types.
- **Chores**
- Clarified and renamed internal types for quick actions to improve code clarity.
