add shebangs to migration and server scripts

In NixOS, we wrap these files in a bash script to allow users to just run them as normal executables, instead of calling them as arguments to Node.JS. In our build scripts, we just add the shebang after the files have been compiled, but adding it upstream will allow all Pangolin users to just run ./server.mjs to start their Pangolin instances.
