The billing module has been refined and enhanced to include deeper validation and detailing of billing plans and products. The checkout session creation process was revised to handle more complex scenarios, incorporating better parsing and validation. Additional validations were added for the plan and product schemas, improving product details extraction, and rearranging of module exports was made for better organization. The code refactor allows easier future modifications and upgrades for recurring and one-time payments with nuanced product configurations.
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.
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.
