fix: enforce parity of sequencer tx validation and node tx validation (…
…#7951) Part of #4781 by having parity between sequencer tx validation and node tx validation. Note that we are using the validators from the sequencer, and they should match. We are omitting `phases` and `gas` tx validator which is in the sequencer and not here is because those tx validators are customizable by the sequencer and not uniform between all sequencers. --------- Co-authored-by: Nicolás Venturo <[email protected]>
