feat: seed existing user for e2e tests

[irby]

Description

As mentioned in #955, I noticed the end-to-end tests do not have a way to test out flows for users that already exist. This is especially important for the end-to-end test when signup is disallowed. I wanted to be able to verify the flow for existing users.

This change will seed a user so we can verify the various flows for existing users in the end-to-end tests.

Implementation

Aside from migrations, there doesn't seem to be an existing solution to seed data into the databases. While I could've created a separate process within the hanko backend to handle seeding, since this behavior was not requested I decided to not add any functionality to the backend. Instead, I created a SQL script that will be executed by a seeder Docker container after the migrator container has added migrations. The script has constant values it will add into the database, including a user with the email [email protected] that will be used by the end-to-end tests.

Tests

Added tests within the nosignup, pw and nopw tests to verify the flow of existing users and what the next screen they see would be after they login.
