• Speed up Has-Voted
• Speed up Hasn't-Voted -> articulated requirements better here: https://voteagora.atlassian.net/browse/ENG-1912 (ie, we are going to split up / filter the display of users/apps/chains)

We have a PR up, that previews has-voted and hasn't-voted with ~1 second queries for both.

Albeit, we're adding filters ASAP.
