This commit removes the redundant `use-toast.tsx` file and refactors the authentication methods in `personal-accounts-server-actions.ts` to enhance service integration and data handling. UI components like `LanguageDropdownSwitcher` and `site-header-account-section.tsx` have been refined for better readability. Changes in the `config.tsx` file aim to improve the overall code cleanliness. The `schema.sql` file under migrations was updated to cascade delete for 'invited_by' reference.
Deleted the billing-redirect-button, checkout-redirect-button, and embedded-stripe-checkout components. Additionally, removed the shadcn directory, which encompassed billing-related icons. This change streamlines the subscription settings interface and organizes the system's payment management. This update is a stepping stone towards improving the billing system's overall architecture.
Created a new package named billing-gateway which implements interfaces for different billing providers and provides a centralized service for payments. This will potentially help to maintain cleaner code by reducing direct dependencies on specific payment providers in the core application code. Additionally, made adjustments in existing services, like Stripe, to comply with this change. The relevant interfaces and types have been exported and imported accordingly.
