fix: portal/app build + Prisma Docker build failures

1. Portal & App: Add @comp/company build to prebuild step so the
   compiled dist/ exists before next build runs. The package exports
   compiled JS but wasn't being built during Vercel deployments.

2. API Dockerfile: Bypass prisma.config.ts during db package build.
   The earlyAccess multi-file schema config conflicts with the
   --schema=dist/schema.prisma flag on the Linux Prisma engine,
   causing a panic in the relation walker. Temporarily renaming
   the config during generate avoids the conflict.

3. API Dockerfile: Update production stage Prisma from 6.13.0 to
   6.18.0 to match the version in packages/db/package.json.
