r.get() crashed when the Caddy API returned a routes array containing
string elements. Added isinstance(r, dict) check and also made the
match[0] traversal safer by using any() over the match list.
The old message just said 'expose manually if needed' with no guidance.
Now it prints the exact docker commands to publish the port directly
and how to find the container IP for a custom reverse proxy.

docker run fails hard if the path passed to --env-file is missing.
Make the flag conditional so apps without an env file (or where the
file hasn't been created yet) still start successfully.
