Component Sidebar: Manage tab

[jmakowski1123]

To be completed after: #1045

1. The Manage tab contains two collapsible spaces - Publish Status and Tags. Both should be opened by default when the Manage tab is clicked.
2. The Publish status contains the following data: Publishing Status (Published, Draft, Unpublished changes); time stamp when the draft was last auto-saved.
3. Out of scope - release date and visibility settings.
4. The Tags space cannot be developed until Epic 5; for now, the space should just exist.
