• [x] Rename components suffixed with Field to Input
• [x] Details component - Rename PatientInformation to PatientDetails and refactor implementation
• [x] Subform components - Rename PatientDemographicsForm to PatientDemographicsSubform, PatientMedicalForm to PatientMedicalHistorySubform, and refactor implementations
• [x] Form component - Rename PatientInformationForm to PatientDetailsForm and refactor implementation
• [x] Connector component - Create PatientDetailsConnector
• [x] Conversions - Create conversions module

KEEP IN MIND

Validation and conversions should be treated as a form level concern, not on each field or input.
