fix(scripts): name the probe's case loaders off the self-test anchor

dispatch-gates' self-test anchor reads any function whose name spells
self-test as a self-test entry and wants each compound one ledgered.
These two only load and register cases into the drift script's own
self-test, so they are renamed (registerProbeCases, loadProbeModule)
rather than ledgered.
