[gitlab-org/gitlab] Improve display of work items on Milestone page

### ROOT CAUSE The current card design in the Milestone view's Work Items tab prioritizes project/group names over work item details, making it less user-friendly. The project/group name is displayed prominently (bold and first), which is not the focus for most users. This design inconsistency with the issue/epic boards creates visual clutter, especially when group names are long or multiple work items share the same group. ### CODE FIX Modify the card template in the Milestone view to align with the issue/epic board style: 1. **Update the card structure** in the Vue component (`app/assets/javascripts/ee/mixins/work_items/milestone_work_items.js.vue` or similar) to remove project/group emphasis: ```javascript // Replace the current card template with: ``` 2. **Adjust the data binding** to ensure only work item details are displayed. Remove any hardcoded project/group references in the template. 3. **Update the backend API** if necessary to ensure work items are passed with their full details (title, description, etc.) and not filtered by project. 4. **Test the changes** to ensure the card layout matches the issue/epic boards and does not break existing functionality (e.g., filtering, sorting). This change will prioritize work item content over project metadata, improving usability while maintaining consistency with other boards.
