🐛 Fix ArgoCD App State Validation workflow

- Fix curl error (exit code 23) by downloading to /tmp first
- Add PR branch/repo detection for bootstrap step
- Dynamically generate root-app.yaml with PR context
- Use GITHUB_HEAD_REF for PR branch detection

This fixes the failing CI check by:
1. Downloading ArgoCD CLI to /tmp to avoid permission issues
2. Detecting the correct PR branch and repository
3. Bootstrapping ArgoCD with the PR's repo/branch
