feat: build a real UCAuth

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.
