ClideCollapserCard and ConversationCard sat adjacent but used different
tokens for the same roles, so labels/summaries rendered 1-2px apart.
Standardise both on label = clideFontCaption (14), collapsed summary =
clideFontMeta (13): bump ConversationCard's label up from clideFontSmall,
bring the collapser's summary down from clideFontCaption. Goldens
regenerated for the affected card images.
