handle healthcheck.disable true in isServiceHealthy

[stavros-k]

Func ToMobyHealthCheck converts disabled helthchecks to []string{"NONE"}.
Made changes in isServiceHealthy, to also consider the above as "no healthecheck", as it will never be nil

	if check.Disable {
		test = []string{"NONE"}
	}

Additionally added some unit tests. To be honest, the tests ONLY were generated by AI.

I used the following code to test. Before my changes it would fail, after my changes, not.
