fix: Local patient not syncing after profile update

[MarcuX009]

This PR updates the logic in ProfileViewModel.saveProfile() to ensure that the local patient property stays in sync with the backend after saving.

Specifically, it uses store.updateAnyPatient(...) and casts the result back to OCKPatient, then assigns it to self.patient to trigger the willSet block and properly refresh local fields such as firstName, lastName, birthday, etc.

• Fixes an issue where local patient data was not updated after a successful backend save

Looks good, but quick question/ask

[cbaker6]

Technically, this should automatically update the patient in PatientView here:

CareKitSample-ParseCareKit/OCKSample/Main/Profile/ProfileView.swift

Lines 88 to 90 in f8e82a4

	.onReceive(patients.publisher) { publishedPatient in
	viewModel.updatePatient(publishedPatient.result)
	}

But, the way @CareStoreFetchRequest currently returns OCKAny... which doesn't conform to Hashable inside CareKit, it's possible the view doesn't receive the updated OCKPatient from @CareStoreFetchRequest

LGTM!
