Proto: extend consistency checks for scoru constants

Context

Closes #2980 (closed).

The checks comes from my understanding of the constants and I tried to give a explanation of the values in the different commit messages.

Manually testing the MR

We could obviously write a test that test the check itself by starting a chain with the wrong constants, but I don't know if it makes a lot of sense. Although, I don't know if that's doable but I could try to write tests for start a smart contract rollup with constants which does not respect these constraints and see how it breaks the invariants.
