REFACTOR(repo): migrate to Helm chart structure

- Add web-app Helm chart in charts/web-app/
- Replace individual deployment/service/ingress YAML with helm-values
- Update ArgoCD applications to use Helm chart with values files
- Reduces per-app files from 6 to 2 (argocd.yaml + helm-values.yaml)

Apps migrated: jaejadle, jaejadle-dev, joossam, joossam-dev,
jotion, jovies, portfolio, todo
