refactor(chart): rename frontend ConfigMap and add config.json key

- Rename configmap-caddy.yaml to configmap.yaml (generic frontend ConfigMap)
- Update helper from *-frontend-caddy to *-frontend
- Add showcase.frontend.config (YAML) rendered as config.json in ConfigMap
- Mount config.json to /srv{baseRoute}/config.json in frontend deployment
- Rename volume from 'caddyfile' to 'frontend-config'
