Add suggestion match details view to React editor.

The old GWT editor can display details of all the matches for a row of translation memory results (i.e. a set of matches that all have identical source and translation text but come from different documents that may be in different projects).

This functionality should be added to the React editor, showing similar information.

The old details view has a dropdown with each of the locations that the matching source+translation are found, and details for the selected location. Details include source text, source comments, translation state and text, and translation comments.

Technical notes

• Design and react component
• Needs REST API, DTO for tm details
• Does not have bookmarkable link to the translation (implement as separate story)
