fix(orchestrator): rm dangling symlink before COPY in Docker builder

Kaniko resolves destination symlinks during COPY. Writing to
apps/orchestrator/prisma/schema.prisma (a symlink → ../../api/prisma/schema.prisma)
causes kaniko to try to resolve /app/apps/api which does not exist → build fails.

Fix: RUN rm -f the symlink first so the destination path is clean,
then COPY the real schema file to that location.

CI is unaffected (symlink resolves correctly in the monorepo checkout).
