Add Feature: Dynamic Radar Chart with FHIRPath Processing

[raikm]

Summary

This PR introduces:

• Questionnaires Overview Page in Data Hub
• Related Questionnaire Responses Overview Page with Radar Chart
• API Endpoints for relevant FHIR ressources

Context

The task allowed for some interpretation. I understood that the Data Hub serves as a central repository for different questionnaires, enabling users to explore responses and analyze results over time.

Changes

UI

• Created Questionnaire Overview Page
• Created Subpage for Questionnaire Responses
  • integrated Radar Chart using PrimeVue Chart
  • FHIRPath-based extraction of questionnaire responses
  • Normalized data for consistent visualization
  • Future improvement: match relevant LOINC-Codes (loinc.org/62337-1) for precise data extraction

API

• Refactored User Endpoints for more consistent API structure
• Created new endpoints for Questionnaires and Questionnaire Responses
• Created new service classes for database interactions

Tests

• Created unit tests for the UI
  • ⚠️ Some tests require fixing: Issues related to component mounting
• API Tests not implemented due to:
  • vitest currently not supported see issue
  • Next steps: Identify an alternative API test framework (e.g., jest, supertest)

Checklist of Requirements

• Implementation of Radar Chart: Do you fulfill the requirements?
• Code structure and quality: Is the code well-organized and easy for others to pick up, extend, or maintain, demonstrating thoughtful design and clear intent?
• Documentation: Is it clear what your functions do and how they are used? Do you focus on the key points and strike the right balance of what is too little and what is too much? Do you explain controversial or unintuitive decisions you made?
• Test coverage: Do you test your code?
