fix(tests): EIP-6780, EIP-7702, fork inheritance, chain_id

[pdobacz]

Some fixes from upstream #42 missed initially, 4 independent commits with respective desciptions

Greptile Summary

The PR aligns Monad transaction validation with explicit chain-ID extraction, fixes multiple-fork EIP inheritance, and adjusts EIP-6780/EIP-7702 tests.

• Unions enabled EIPs from every direct non-EIP fork base.
• Adds explicit chain-ID mismatch errors and derives legacy signing hashes from the transaction’s encoded chain ID across Monad forks.
• Makes self-destruct test gas fork-aware and raises a set-code test transaction’s fee cap.

Confidence Score: 4/5

The oversized legacy chain-ID conversion should be fixed before merging because it can abort transition processing instead of rejecting the transaction normally.

The new extraction path accepts a U256 transaction field but narrows the derived chain ID to U64 without mapping overflow into the transaction-validation exception hierarchy.

Prompt To Fix All With AI

### Issue 1
src/ethereum/forks/monad_eight/transactions.py:641
**Oversized chain ID escapes validation**

When a legacy EIP-155 transaction encodes a chain ID greater than `2^64-1`, this `U64` conversion raises `ValueError` instead of an `InvalidTransaction` exception, causing transition tooling to abort rather than record the transaction as rejected. The identical conversion also affects the Monad Next, Nine, and Ten implementations.
