fix: Improve ArgoCD stability by adjusting resource allocation

Problem

ArgoCD is becoming increasingly unstable. After any restart (maintenance or restarting argocd pods to solve sync problems), it takes only a few days or PRs to get back in sync-stuck. Guessing is insufficient resources.

Ideas

We need to:

1. Check current resource settings.
2. Review best practices.
3. Adjust settings to improve stability.

Acceptance Criteria

• Current settings documented.
• Best practices reviewed.
• PR with updated settings merged.
• Monitor ArgoCD stability.

Checklist

• [ ] Document current settings (here in issue)
• [ ] Research best practices
• [ ] Submit and merge PR
• [ ] Monitor improvements
