[reseach aggkit] Check if `aggsender-validator` have more requirements for support L2 full-node RPC

[joanestebanr]

aggsender-validator use almost the same functions as aggsender. It need to validate that there are no other call that require a archive node

[joanestebanr]

Main difference between aggsender and validator is the way to calculate the first block of a certificate:

• Aggsender: calls to GetLastSettledCertificateToBlock(certHeader)
• Validator: do an extra call to certificateQuerier.GetNewCertificateToBlock(fullHeader)
  The main difference is that aggsender don't have the importedBridges included in certificate and ask for latest to agglayer, in the case of validator have all of them and check for each to which block belongs using bridgesyncer.GetClaimsByGlobalIndex(ctx,globalIndex) that use DB data

The rest of calls are also used by aggsender so the conclusion is that doesn't have any specific requirements
