[PM-12012] Save region during account creation

[andrebispo5]

PM-12012

📔 Objective

This update addresses an issue with the account creation process, which is divided into two steps. Currently, users can change the application region before completing the second step, potentially leading to registration in a different environment from where they began.

To resolve this, we are now saving pre-authentication URLs alongside the email address in the application state. These URLs will be loaded when the user initiates the completion of their registration, ensuring a consistent experience throughout the process.

🤔 One caveat is that one could create two accounts in different regions using the same email which would result in the last one receiving both actions from the verification email. I guess it's an extreme edge case but wanted to point it out.

🤔 What do you think about changing the name of getPreAuthEnvironmentUrlsByEmail (and setter) to something like getPreCreationEnvironmentUrlsByEmail? Because as far as I see this is used in creation. I'm also fine if you want to stick with the current name but maybe it's clearer the other way.
