Delayed / missing log output when running dev container image

[j-mueller]

• When running the image with docker run -p 8080:8080 ghcr.io/j-mueller/wsc-poc-mock-server:latest. No log appears.
• With podman run -p 8080:8080 ghcr.io/j-mueller/wsc-poc-mock-server:latest, we get a line saying Starting mock server on port 8080 only after exiting with ctrl-c.
  • This is the expected output, but it should appear right away, not when terminating the process

Not sure if this needs to be changed in Haskell or podman / docker.
