chore: fix local development

[atarashansky]

Fixes local development bug introduced in #500

Debug mode wasn't set properly as the CLI was updated to use the default config, in which debug is set to false. I updated launch_dev_server.sh to use -d flag to set debug.

I also added localhost as an allowed origin when debug is true.
