Ethereum Stop Sequence

[MicahMaphet]

🛑 Description

Previously when using ethereum on bitcore-node, the server would never stop. This was caused by the ethereum rpcs not stopping. This solves this by tearing down rpcs after the worker stops all the services

🪵 Changelog

• Tear down rpcs after the worker stops the services in all, api, and p2p

🧪 Testing Notes

Tested with a bitcore.config.json that only uses ethereum.
Run, and stop on master and eth-stop:

$ npm run p2p
[press ^C after ETH:regtest up to date message]
info :: 2026-05-08T06:27:30.011Z :: ETH:regtest up to date.
^Cinfo :: 2026-05-08T06:27:33.530Z :: Shutting down P2P pid 55016
