Add testnet4 branch to contrib history script
Testnet4 uses a different default electrum port than testnet.
What changed, and why it matters
This commit adds support for Bitcoin's new 'testnet4' network to a helper script called contrib/history.py. It simply tells the script which TCP port to use (40001) and which pycoin network symbol to import. There is no security issue visible in the change.
No security action needed. Reviewers may optionally verify that port 40001 and the xtn pycoin symbol are the correct defaults for testnet4, but the change itself is benign.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff extends an existing if/elif chain in contrib/history.py to handle the ‘testnet4’ network argument. It assigns port 40001 and reuses the existing pycoin testnet symbol (xtn). The change is additive, follows the existing pattern, and does not modify any server-side code, authentication, parsing, or network-handling logic.
