feat(user): implement BDD e2e tests for registration

[abhiram-art]

Description

This PR completes the BDD end-to-end test scenario for user registration, as described in issue #520.

It connects the frontend and backend layers through WebDriverIO and finalizes the register.feature flow to ensure the user registration journey is properly tested end-to-end using Behavior Driven Development (BDD) style.

@abhiram-art did you set up the keycloak api key in the user api side? As we mentioned here: https://greenstand.slack.com/archives/C05TVUSEQQ0/p1755746182523629
And here:

[pierrelstan]

@abhiram-art The key PRIVATE_KEYCLOAK_CLIENT_SECRET is supposed to be private, right?

[abhiram-art]

@dadiorchen yes, I entered the client secret while setting up the project at the beginning.
