Using pnpm start in local Docker deployment causes issues with PostHog and Supabase

[daryllimyt]

Describe the bug
This is relevant to local prod deployments. When running pnpm start inside of Docker causes errors initializing Supabase and Posthog. Supabase looks for url and key, and posthog fails to initialize.

To Reproduce
Steps to reproduce the behavior:
Overwrite the docker entrypoint command for frontend/Dockerfile (either in the dockerfile or in docker-compose.prod.yaml) to use pnpm start, and set NODE_ENV="production"

Expected behavior
It should run normally and load the app

Additional context
Workaround is to just use pnpm dev, even though we're using a multi-stage build and actually building the nextjs project with pnpm run build

I have a draft PR that may help with the posthog issue: #58 , feel free to use this as a starting point.

Supabase no longer relevant, open up in the future if posthog issues persist
