[FIX] gamification: perf on write karma_min on gamification.karma.rank

This commits avoid to call recompute when you write on the rank without
touch the karma_min value.

On write on karma_min, we have 2 cases:
- Rank order are the same, just need to recompute the rank for the user
that could be impacted. Eg. if karma_min changes from 45 to 50, we need
to recheck for all user between 45 and 50 their new rank.
- Rank order are not the same, we need to recompute for all users.
(could be still improved if needed)

When you recompute the rank on a list of users, depending of the number of
users (bulk if more than 3 * number of rank) we check for each user what is
the new rank, or for each rank whats is the new users.

No way to edit a rank on the prod server. Lock sql -> crash server
