Pin ArgoCD to v3.2.6 (#44)

## Summary
- Pin ArgoCD kustomization to v3.2.6 tag instead of `stable` branch
- This gives intentional control over ArgoCD version upgrades

## Deployment and Testing
- [ ] Sync the `apps` application: `argocd app sync apps`
- [ ] Point argocd at feature branch: `argocd app set argocd --revision feature/pin-argocd-v3.2.6`
- [ ] Sync argocd: `argocd app sync argocd`
- [ ] Verify ArgoCD is running v3.2.6
- [ ] After merge, reset to main: `argocd app set argocd --revision main && argocd app sync argocd`
