Replace Require strings with lambdas

[Bushstar]

The adding of Require impacted performance as strings were always created regardless of whether the conditional was true or false. This PR updates all Require statements not with the exception of mn_checks.

Leaving these for context:

We shouldn't have any observable difference from lambas on regular checks that isn't run through expensive calculations like decimal conversions, since it's effectively the same (if anything an additional function call, but that would be micro-opt that we don't need to be concerned about here)

Merging for now, since it's already reviewed and verified, on all tests and PR does cover some impactful areas. However, need to evaluate long term maintainability of this later.
