feat(tests): sign state test transactions with their secret key to prevent bogus sender recovery

[felix314159]

🗒️ Description

this test is useful for reproduction of a nethtest issue (not relevant for mainnet): currently their state-test runner identifies the sender via secretKey but attaches a placeholder signature, so when the sender account is absent from the pre-state RecoverSenderIfNeeded re-recovers a bogus sender from that placeholder and a zero-gas-price transaction then crashes with Account … is null when incrementing nonce. This signs the transaction with its secretKey so recovery yields the correct sender

fill with
uv run fill tests/frontier/touch/test_touch.py::test_zero_gas_price_nonexistent_sender --fork=berlin -v -s --clean

Thanks! LGTM. I think we should wait for #2969 to be merged first, make the changes then merge :)
