fix(traefik): update remote config writing to use base64 encoding

- Modified the `writeConfigRemote` function to encode the Traefik configuration in base64 before saving it to the remote YAML file.
- This change ensures that the configuration is correctly handled and prevents potential issues with special characters in the config.
