/app/data is a bind mount, so the chown baked into the image is
overwritten by the host directory's ownership at runtime. On a fresh
prod deploy Docker creates ./data as root-owned, but the container ran
as the non-root nextjs user, so Prisma couldn't open lovelope.db
("unable to open database file").
Add an entrypoint that starts as root, chowns /app/data, then drops to
nextjs via su-exec before running migrations and starting the server.
