fix: Dockerfile COPY order - node_modules must come after source
Docker COPY replaces directory contents, so copying source code
after node_modules was wiping the deps. Reordered to:
1. Copy source code first
2. Copy node_modules second (won't be overwritten)

Fixes API build failure: "dist not found"
