Fix GitHub Actions CI: Install pnpm before using cache

The GitHub Actions workflow was trying to cache pnpm before installing it.
Fixed by reordering steps in all jobs to:
1. Install pnpm first
2. Setup Node.js with pnpm cache
3. Install dependencies

This ensures pnpm is available when setting up the cache.
