fix(test): correct ha-failover test — wrong URL, wrong pod label, missing kubectl

Browse Source 
Three bugs:
- GITEA_URL defaulted to localhost:3000; Gitea NodePort is 32166
- Pod label app.kubernetes.io/name=postgresql-ha matched pgpool pod too;
  added component=postgresql to target only postgres nodes
- Used bare 'kubectl' which is not on PATH; switched to 'k3s kubectl'
