perf(core/txpool): use the cached address in ValidateTransactionWithState #30208

[gzliudan]

Proposed changes

The address recover is executed and cached in ValidateTransaction already. It's expected that the cached one is returned in ValidateTransaction. However, currently, we use the wrong function signer.Sender instead of types.Sender which will do all the address recover again.

Pull request overview

This is a small performance optimization that replaces signer.Sender(tx) with types.Sender(signer, tx) in ValidateTransactionWithState. The direct signer.Sender() call always performs the expensive ecrecover signature recovery, while types.Sender() first checks a per-transaction cache that was already populated by the preceding ValidateTransaction call, avoiding redundant computation.

Changes:

• Replace signer.Sender(tx) with types.Sender(signer, tx) in ValidateTransactionWithState to leverage the cached sender address from prior validation.
