ModuleProxy::callRemoteMethod is the choke point every cross-module call
passes through on the callee side. It logged the full QVariantList of
arguments at debug level, which dumped secrets — mnemonics, passwords,
auth tokens, key material — into module logs in plaintext.
Log only the argument count, matching the other transport call sites
(LogosAPIClient/LogosAPIConsumer/LocalLogosObject/RemoteLogosObject all
already log args.size() only).
