feat/auth via supabase

[ff6347]

This PR adds authentication using Supabase. All that use supabase are now under /api/v3/[get|delete|post].
We still support the auth using auth0 for a smoother transistion. The api can already be found under https://supabase.api.giessdenkiez.de/

This is a major refactor. I know but we need this to reuse code in routes

I left two comments for you.
The commit where you keep v2 and v3 was quite complex but looked good to me imho.

very good, that you removed some unused routes on the fly :)

(Can't say too much because I'm not overly familiar with this codebase)

Surely challenging to make this migration from one auth solution to another. It looks very thoroughly tested, that's great! If our manual testing is also successful, let's move on with this!

Found one small issue in the README, that's all.

@dnsos @julizet Thanks for your reviews. I guess I will merge this into staging so we can start manually testing this. I also need it to test user import from Auth0.
