fix(mongodb-runner): don't leave a dangling --port flag on secondaries

removePortArg() only removed the value after --port, not the flag
itself, so replset secondaries got both the original --port and a
second --port 0 appended, causing mongod to reject the duplicate flag.

Also fixes two places that only checked args.includes('--port') and
therefore missed the --port=X form: the mongos random-port retry
logic and the default --port 0 injection. Extracted a shared
hasPortArg() helper in util.ts to avoid duplicating this check.
