Issue/504 add auth

Pull Request

Description

Add Auth0 integration and corresponding endpoints/auth loading state/logout page:

Fixes #504

N.B. also includes small fix for nowcasting-app as the SSR wasn't passing Cypress tests with date string formats being different between prerender on server and render on client-side, causing a React hydration error. Have forced the component to render client-side for now, but may need to keep an eye on this for date/time stuff.

How Has This Been Tested?

Locally and Vercel preview branch:

Node CI error?

[peterdudfield]

Code looks great, and app seems to be working

Ive just left a few comments, do you mind looking at them?

Node CI error?

@peterdudfield Yes – this needs a bit of tinkering to get Cypress to run properly in the CI – I think I got most of the way there but need to revisit when I get a chance... is an expected error atm and it runs pre-commit successfully so should be okay in meantime
