fix: ensure deterministic probation list encoding (#4786)

Map iteration in Go is non-deterministic. ConvertProbationListFromState
iterated over ProbationInfo map directly, producing non-deterministic
output ordering. This fix sorts the map keys before iteration to ensure
consistent, deterministic encoding.
