fix: stop ignoring scripts/ in .dockerignore

The new docker-entrypoint.sh lives in scripts/, but .dockerignore was
excluding the whole folder from the build context — so the COPY in the
Dockerfile resolved to a missing file:

  COPY scripts/docker-entrypoint.sh: not found

Removing the `scripts/` line lets the build context include it. The
other ignored paths stay (node_modules, .next, .git, env files,
Dockerfile, docker-compose, nginx, certbot, prisma dev.db) — those
genuinely don't need to be sent to the daemon.
