Rebased on latest main (ad95d8c) to include #4934, to make testing this more straightforward.

I tried reindexing testnet chain data with args --indexing-denom passet14h46dmcyy6fl5vyz7xx933n8l7jy202ahrxg92kad6yfladsvcyqczcwda --dex-ex-min-liquidity 1000 and then ran the dex-explorer interface against that local db. I'm still seeing "no summary found" for the UM/TestUSD pair, though:

I'm certain there's liquidity there, because when I view my own LPs:

The dex explorer can display summaries for gm/gn just fine:

Am I wrong to assume that using this PR would affect summaries in the dex explorer? Should I instead be trying with the insights app?

hmm, I'm going to try this on my end as well ; a priori I'd expect it to start working 🤔 Checking insights would be good as well

I pushed a commit which fixed unrelated issues with the behavior of the summary tab for assets with infrequent trading.

I don't think the dex explorer frontend has the relevant page where this overriden value matters, which is the "aggregate summary" page (where "explore" will point to)
