docker-compose: force ASPNETCORE_ENVIRONMENT=Production on runtime

.env contains ASPNETCORE_ENVIRONMENT=Development, which gets
loaded via env_file into every service. With ASPNETCORE_ENVIRONMENT=Development, ASP.NET Core loads appsettings-org.Development.json — which has a Kestrel:Endpoints block binding BOTH http://localhost:5000 AND https://localhost:5001. The HTTPS endpoint has no cert on a fresh host, so Kestrel crashes with:

  fail: Microsoft.Extensions.Hosting.Internal.Host[11]
        Unable to configure HTTPS endpoint. No server certificate
        was specified, and the default developer certificate could
        not be found or is out of date.

Fix: add an explicit ASPNETCORE_ENVIRONMENT=Production to each
runtime service's environment: block. In Compose, literal
environment: entries override env_file: entries with the same
name, so this wins over .env's Development value.

Production-loaded appsettings-org.json has no Kestrel block, so
Kestrel uses only the ASPNETCORE_URLS env var we already set
(http://+:5000 etc.) — HTTP only, no HTTPS crash.
