Clean up initialization code for server

[horner]

We should make /data not hard-coded. The code right now assumes that you're running in a docker container, unless you have a .env file. We should make the code fail if the work-dir is not available (or ask if you want to make it).

The older code always made a work dir in the cwd and it was painful to launch and then start the download if you accidentally were in the wrong directory.
