feat(loading): enable loading screen to be overriden
For that just provide your own ./loading/index.html Then in vue3, you can also override dynamically the error view for disconnect or disconnect-with-reconnect. You just need to define layout for "error" and "error_reconnect". Also a variable "trame_error_report_msg" will be available for you to leverage in your custom template.
