shipped a new version of the top mini apps algo

- momentum: mini apps that are growing hourly / daily / weekly will get boosted, this gives new apps a better shot of climbing up the leaderboard
- dynamic: momentum also makes this algo much more sensitive to changing trends, expect to see more variability based on what's hot
- open: the previous algo was tied to rewards, this has the negative impact of apps being missing for reasons like being in a jurisdiction we aren't able to pay rewards to, now all apps get scored

more to come here soon
