Resolve "Ensure Patient ID does not contain any spaces"

What does this MR do?

This MR adds a validation to the patient ID, to check for whitespaces (space/tab) anywhere in the ID (leading/trailing/sandwiched?). This did require some changes to the annotations used in the PatientCreateDto, as some annotations were not valid, e.g. @NotBlank on a non String or @NotBlank on token that is always blank when creating a patient, the token is generated afterwards.
