Remove team account related services and actions

Removed services and actions related to team account deletion as well as updated paths within other dependent files, better reflecting their new locations. Also, added a new service titled 'AccountBillingService' for handling billing-related operations and restructured the form layout and handled translation in 'team-account-danger-zone' component.
