feat(purchase): add checkout expiration settings and reservation status to purchase items

- Introduced a new configuration file for purchase settings, including checkout and payment expiration times.
- Added a migration to include a `reservation_status` column in the `compra_items` table, defaulting to 'active' and updating existing records based on purchase status.
- Created a migration to add an `expires_at` timestamp to the `compras` table, updating it for existing records based on their status.
- Scoped unique indexes in the `carritos` table to only active carts, adding virtual columns for active user and guest tokens.
- Implemented a console command to expire overdue purchases and release stock reservations, scheduled to run every minute.
- Added tests for Google token exchange and login functionality, ensuring proper cart handling and user authentication.
- Updated purchase-related tests to reflect changes in item handling and customer data validation.
