Error Details: Failed to fetch

## The problem

Reported in Daytona: Error Details: Failed to fetch.

## The fix

On a self-hosted Daytona (docker compose), if the dashboard at port 3000 shows 'Error Details: Failed to fetch', the dashboard cannot reach the auth service. Fix: expose authentication to the dashboard by setting PUBLIC_OIDC_DOMAIN=[your_auth_domain]:5556/dex in the API service environment, then restart the API service. Maintainer-provided.
