Let's add a new use case to the Auth app.
We'll add a sign up use case with email and password.
Check the existing SignIn use case to implement it.

You need to persist the use case.
Check examples/apps/Spotify/src/ucds/CreateAlbumServerMain.ts as an example to see how to do so

<interrupt>

Do not change SignUpOPI0. Only return jwt.
Also you need to persist before assigning auth so you can update auth.user.id with the aggregateId

Now remove the usage of the default roles, remove the role input field and set the role to "regular" by default when a user signs up.

Do not use FAKE_USER_REGULAR anymore.
Build a proper UCAuth.
For the organizationId, generate one using CryptoManager.
For the firstname, capitalize the first part of the email address (before arobase)

THIS IS A NIGHTMARE. LOOKS LIKE SOMEONE WHO LIED ON THEIR RESUME, TRYING TO SOLVE A SIMPLE PROBLEM DURING AN INTERVIEW.
