Is your feature request related to a problem? Please describe it

mantis init doesn't handle setting the db url; therefore, the generated app doesn't work until a apps/server/.env.local or similar is added with contents like the following.

# Example
MONGODB_URI='mongodb+srv://<user>:<password>@<cluster-name>.mongodb.net/?retryWrites=true&w=majority'

Describe the solution you'd like

mantis init should prompt the user for a db url to use during generation. It should also create a apps/server/.env.local file with the following content so the user doesn't have to create one themselves.

MONGODB_URI='<the url given>'
