Subject: [PATCH] fix: call closeAllConnections() before server.close()

server.close() only stops accepting new connections but does not
terminate existing keep-alive connections. This can cause the cleanup
promise to hang indefinitely in test suites or production.

Add server.closeAllConnections() (Node.js 18.2+) before server.close()
in both single-account and bulk cleanup paths.

Addresses greptile review feedback.
