Split transactions from inclusion lists into hash+sidecar pattern
This PR modifies FOCIL to use transaction hashes in the signed inclusion lists instead of full transactions, with full transaction data traveling as sidecars during P2P propagation (similar to EIP-4844 blob sidecars).
Key changes:
Why this matters:
Proposers can now efficiently prove IL equivocation without needing access to complete transaction data - they only need the conflicting hash lists. This reduces bandwidth on the consensus layer while maintaining full transaction availability through the sidecar mechanism. We could also use it to do more sophisticated stuff on the networking layer such as pulling the full-tx sidecare instead of pushing in case the hashes are not already available in the mempool.
