fix(prover): Reorder guardian prover sign + add allowance flag/logic

[cyberhorsey]

make sure L1 origin is synced for block ID before trying to sign the block hash, and add logs.

this also adds an allowance flag for the prover, which should both mitigate a LOT of devrel related help (as every day many people ask for "how do i set allowance" and "how much should i set", so we can set a sane default in the docker scripts), and let us have easier internal deployments so we dont have to approve every internal l1prover manually.
