fix(deploy): force dev deps in Docker deps stage; commit prod NEXT_PUBLIC_*

Coolify injects NODE_ENV=production at build time, causing
`pnpm install --frozen-lockfile` to skip devDependencies. Next.js
build then fails on missing @tailwindcss/postcss.

Override NODE_ENV=development and pass --prod=false for the install
step only. Builder stage still runs `next build` with
NODE_ENV=production, which is the intended runtime mode.

Also commits apps/dashboard/.env.production with public URLs so
Next.js bakes NEXT_PUBLIC_* into the bundle at build time (Coolify
API rejects the is_build_time flag, so we can't mark them runtime).
