• This PR has a title that briefly describes the work done, including the ticket number if there is a ticket.
• My work conforms to the OpenMRS 3.0 Styleguide and design documentation.
• My work includes tests or is validated by existing tests.

Summary

This PR adds a new validator that disallows entering decimal values in number fields based on the optional disallowDecimals property in a question definition.

This feature is necessitated by how numeric concepts can specify whether they allow decimal values or not:

Presently, the number rendering type doesn't provide any validation for decimal values (nor does the Carbon NumberInput which is what it's using under-the-hood).

With this new validator, form authors can tack on a disallowDecimals boolean property to the question definition for a number field and set it to true if it doesn't allow decimals. Once set up, the form engine will show an error if a decimal value is entered in the field.

This fix addresses an ongoing issue with the Laboratory Test Results form in the reference application. Filling the form with decimal values that lie within the reference ranges for those concepts yields an error when the form is submitted:

This error is directly related to number fields not allowing decimal values. In this case, the fields that don't allow decimal values are:

• Platelets
• Neutrophils (%)
• Mean Corpuscular Volume
• Lymphocytes
• Combined % of monocytes, eosinophils and basophils
• Serum sodium
• Total protein
• Serum Glucose (mg/dl)
• Serum glutamic-oxaloacetic transaminase
• Alkaline Phosphatase, ALP (U/L)
• Amylase (IU/L)
• Serum Carbon Dioxide CO2 (mmol/L)

Once this gets merged in, the next step is modifying the Lab Test Results form schema so that questions linked to concepts that don't allow decimal values have a disallowDecimals boolean property set to true in their question definitions.

@gracepotma do you know why the Amylase (IU/L) question is included twice on the Chemistry page of the Lab Test Results form? Was it added by mistake?

Thanks @denniskigen LGTM 🤝
