As an editor I want to see which references exist for the statement I'm about to edit in order to judge if I need to update or remove them.
**Mockups:**
View when there is only one reference:
{F30407566}
View when there is more than one reference:
{F30407567}
**BDD**
GIVEN a statement with one reference
WHEN editing it in the Data Bridge
THEN I see a references section with the reference
GIVEN a statement with more than one reference
WHEN editing it in the Data Bridge
THEN I see a references section with one reference
AND the remaining references are collapsed behind a "view more references" toggle
**Acceptance criteria:**
*
**Notes:**
* All snaks of a reference are concatenated with TBD
* Reference snak values linking to entities are formatted as links to these entities unless they have a sitelink on the client (tech note: do what the formatter for Lua does)
