Add logging using morgan

[miniBill]

This adds a dependency, so I'm not sure if you'd like it for the template, but I think it's useful to have logging of the requests

Thanks for the PR! Adding logging with morgan is definitely useful in many projects.

For elm-pages-starter-express, I want to keep things as lightweight and flexible as possible so developers can choose tools based on folks' needs. While morgan is a solid choice, I’m aiming to avoid adding specific dependencies unless they’re absolutely necessary for most users.

Feel free to use morgan or any other logging solution in your setup. I use pino in my production setup and it's worked great. I'll leave this PR open for now to see if others think logging should be a part of the project.

Thanks again for contributing!

Yeah, I split my edits into multiple PRs so you could pick the uncontroversial stuff and then we can talk about the less obviously needed ones 👍
