**Is your feature request related to a problem? Please describe.**
This application is deployed in an aspire project but does not output any opentelemetry data.

**Describe the solution you'd like**
A complete integration / support of opentelemetry so that logs / requests / responses and basically all interactions with the service can be tracked

**Describe alternatives you've considered**
A clear and concise description of any alternative solutions or features you've considered.

**Additional context**
Add any other context or screenshots about the feature request here.

Start by locating the API service entry points and current logging and request-handling paths in the repository. Clarify the required OpenTelemetry scope for Aspire, including logs, requests, responses, and other service interactions; the work is done when those signals are emitted and can be observed in the deployed Aspire project.
