Draft: web: improve main page UI
Improve the main page view (OverviewPage).
- Update the header navigation styles and let the header persists across all page views.
- Update text content in Backport component.
- Remove meta title and title computed prop because the header text will persist.
- Use CdxMessage to display the interaction with a warning status. The job needing interaction is linked on the main page.
- Ensure the interaction displays on the main page.
- Format the command text inside JobHistory to have capitalized first letters.
Further improvements to JobHistory will be done in a separate patch.
