fix[authentication]: Support StackBlitz

[FossPrime]

• On AuthenticationService.setup, The error suppression is necessary as without publish, you'll also get errors when login out.
• disables validation and signing of JWT. This works surprisingly well... nothing is lost feature wise, aside from allowing others to spoof login, but that's not a concern in StackBlitz as WebContainers can't be hosted publicly. WASI runtimes run on bare metal and would not have an issue or be affected by this code.
• performance impact is undetectable, as jwt.sign is a usertime function, and this boolean check is a computer time check of the fastest order.

P.S. I was working on a fine example for far too long, but the lack of ESM exports has ruined my day.
