refactor(primitives): simplify FromRecoveredTx by delegating to from_recovered_tx

[samlaf]

Same fix as that from SeismicSystems/seismic-evm#42

Not sure if there was an issue here, but its just unnecessary duplicate code that is likely to contain a bug like it did in evm.

Refactors FromRecoveredTx implementation to delegate to TxEnv for standard transaction types, reducing code duplication.

Phase 1
crates/seismic/primitives/src/transaction/signed.rs:220 — tracing::debug!("from_recovered_tx: tx: {:?}", tx) logs the full SeismicTransaction<TxEnv> with Debug formatting. For confidential transactions (type 0x4a), the TxEnv's data field contains encrypted input that should be treated as sensitive. Consider logging only the tx_hash or using a custom formatter that excludes the data field.

LGTM — The refactoring properly delegates standard transaction types to TxEnv::from_recovered_tx(), eliminating manual field mapping. The Seismic transaction handling remains manual with a clear TODO explaining the dependency on seismic-evm PR #42. The authorization_list change for EIP-7702 appears correct since the Either import was removed and compilation succeeds.
