Replace session with user in team accounts

This commit replaces the session object with the user object in the team accounts feature. This change is reflected in the team-account-danger-zone, layout, team-account-workspace, and billing components. The usage of the user object provides more specificity and accuracy in handling user information compared to the more generic session object.
