Full app scaffolding, self-provisioning, and self-deploying

Today I got the self-provisioning script done. After fighting with Caddy, AWS and DNS for a few hours, it was much smoother sailing to improve the app boilerplate, and finish up the deployment scripts.

I think this can officially be considered V1 now. There's more I want to do in future (e.g. re-look at using Laravel Octane, with some safeguards) but it's not necessary.

It's also 2am here, so I'm going to bed. Toybox will become public soon!
