fix(orchestrator): copy schema file after COPY to overwrite dangling symlink

Kaniko does NOT follow symlinks — it copies them as-is. The symlink
apps/orchestrator/prisma/schema.prisma → ../../api/prisma/schema.prisma
becomes dangling inside the container since apps/api/ is not present.

Fix: explicitly copy apps/api/prisma/schema.prisma to
apps/orchestrator/prisma/schema.prisma AFTER the COPY apps/orchestrator
step. This overwrites the symlink with the actual file content.

CI still works via the symlink (full monorepo checkout resolves it).
Docker now has the real file at the expected path.
