Update authentication methods and UI components, remove redundant file

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.
