WS-516: UI for showing ingestion complete (archived status)

Request page

• Added "ARCHIVED" badge that will appear if the ingested boolean flag is set in the database; also updated timestamp formatting
• Separated input file list markup into new capability-request/files component; added "no files exist" message if active version has no files associated with it
• Moved request operations (create new version button, submit button) into separate component; did some restyling
• Updated styling and refactored out the newly organized components

Sandbox

• Modified sandbox styling to match up more with request page styling

Other

• Added capability request's ingested boolean to front-end model and back-end JSON serialization
