Ready for review, should be feature complete including authentication. Except for the outgoing events, those have to be added, but i am planning to do this in another PR.

So, these are a lot of rather major changes, so I decided to postpone testing until answers/fixes.
Also, at that point please provide me with the GraphQL schema, as I have no working rust infrastructure locally, and do not want to have that much fun with docker exec :)
This makes testing the stuff with the gateway a lot easier

Also, please fix the Gropius issue

The Devcontainer would be an easy way to get the schema. There you can run cargo run -- --generate-schema in the terminal then. But, i will send you the schema once i have made the requested changes.

TODO:

• Fix multiple key fields on 4 entities
• Remove User.userAddressIds
• Remove all non-id-fields from non-resolvable entities
• Rename Address to UserAddress
• GraphQL correct client schemas to fix CI

GraphQL correct client schemas to fix CI

Should be fixed, except for the missing schema transformation step to fix the CI

One comment left, will probably approve after answer/change

• ProductVariant still has fields currentVersion and isPubliclyVisisble which must be gone
• ProductVariantVersion still has fields price and taxRateId which must be gone
• TaxRateVersion still has fields rate and version which must be gone
