Enhancements to the Allergies Form

Requirements

• 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.
• I checked for feature overlap with existing widgets.

Summary

Wide-ranging enhancements to the Allergies form. These include:

• Displaying the patient details header above the form when in tablet mode.
• Rendering allergens and reactions in a two-column layout when in tablet mode.
• Applying a lot of style fixes based on the available designs.
• Disabling the Submit button until a user has selected an allergen to avoid invalid submissions (the allergen field is required). Additionally, should the user check the Other allergen field, we now check to see that they've provided an allergen name in the text input that appears before enabling the Submit button.
• Code improvements that include:
  • Better type annotations.
  • Deleting unnecessary styles and types.
  • Limiting the specificity of certain SASS style overrides so they don't pollute the global scope.
