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.
This commit accomplishes a few modifications including the elimination of `use-toast.tsx` due to redundancy. The authentication methods in `personal-accounts-server-actions.ts` were refactored to improve service integration and data handling. Additionally, UI components were updated for better readability and clarity. Cascading deletion was enabled in the `schema.sql` file for 'invited_by' reference.
