Make rate limit for migrations less strict

[sugar700]

Summary

Change i/move endpoint rate limit to something like 10 users per hour.

Purpose

Currently i/move endpoint has a rate limit configured to 5 per day.

This is problematic, as there are various reasons why migrations could fail, and if the button is clicked a lot despite not fixing issues, it's necessary to wait an entire day afterwards. I saw a lot of cases of people hitting this rate limit due to not understanding the process well.

I don't think making rate limit less strict is a problem, as overall the migration process is pretty cheap if it fails, doing one remote look-up at worst.

It gets a lot more expensive if all the early checks passed, however this mostly doesn't matter, as the account cannot migrate once already migrated.
