ci: move url/input args from datamodel-codegen config to poe tasks

Remove `url` from [tool.datamodel-codegen] config and pass it explicitly
via --url/--input in poe tasks. This eliminates the sed workaround in
generate-models-from-file and prevents --input from being silently
ignored when url is set in config.
