fix: Backend S3 Config + Frontend Health Check Logging & Stability Improvements

[jstevens888]

Description

This update introduces backend configuration for AWS S3 storage and enhances frontend backend-health validation with improved logging and error handling.

Backend Changes

• Added S3 bucket configuration:
  • aws.s3.bucket-name=careconnect-uploads-791068988278
• Enabled LLM feature flag:
  • careconnect.llm.enabled=true
• Supports upcoming file upload and Bedrock-related integrations

Frontend Changes

• Refactored _checkBackendHealth() in welcome_page.dart
• Added detailed debug logging:
  • Base URL
  • Response status code
  • Response body
  • Parsed health status
  • Error output
• Improved error handling and resilience
• Ensured loading state is consistently reset using finally
• Added slight delay to improve UX during health check

Other Updates

• Incremented app version:
  • 1.0.0+32 → 1.0.0+38

---

Why This Matters

• Provides required configuration for S3-backed storage (BD3/BD4 readiness)
• Improves visibility into backend connectivity issues during app startup
• Prevents UI from getting stuck in loading state
• Supports debugging across environments (local, emulator, deployed)

---

Testing Notes

• Verified /v1/api/test/health endpoint returns healthy
• Confirmed logs output correct base URL and response data
• Validated UI properly reflects backend health status
• Tested failure scenarios (timeout / non-200 response)
