feat: update footer and header

[KristinAoki]

JIRA Ticket: TNL-10751

• The library-authoring header matches the header in course-authoring (non-xblock-editor pages) in style
• We want the Library authoring header to look like the course authoring does.
• We should make it easy for changes to the studio header to be reflected in any learning contexts. We should make a single source of truth for “studio headers.“
• child components can be passed in to the shared component, injecting a different menu or other feature.
  • If possible frontend-component-header should be the place to make more flexible.

This PR removed the header and footer in this repo and replaces them with the ones from frontend-components-footer and frontend-components-header

Testing
NOTE: The "Import" page before this change did not properly handle the header. The fix for that issue should be separate task to resolve.

1. on home page and create page, header should only have studio icon and user menu
2. on all other screens, the dropdowns should be as follows
   • Settings
     • Details
     • User Access
     • Import

This PR is dependent on #328. The test need to be fixed and merged into this PR.
