[Gabe-Torres]

🔗 Issue

#1227

✍️ Description

This update utilizes Devise's after_update_path_for method to handle
user redirection after updating their registration.

If the user is part of the adopter or fosterer roster, and associated
with a valid organization they will be redirected to their adopter/fosterer dashboard.

If the user is an admin or super admin, and associated with a valid
organization they will be redirected to their staff dashboard.

If neither condition is met, the user will be redirected to the root path.

Adds: Controller tests for user registration updates:
Test case for adopter/fosterer user redirection.
Test case for staff user redirection.

Adds: update on registration test file to account for new update redirect
