#0000 - Add custom node selectors and tolerations for Traefik deployment

This commit introduces a Helm values file for Traefik to define node selectors and tolerations for targeting specific nodes. The installation script is updated to use the new values file, allowing more precise scheduling of Traefik pods. Additionally, a safeguard is added to namespace creation to prevent errors if it already exists.
