This commit includes significant changes to the layout and presentation of billing related components. The most notable updates are replacing the static back button in 'billing-session-status.tsx' with a fully clickable link button, and improving the product description lookup to use i18n in 'current-subscription-card.tsx'. Additionally, the general structure and spacing of elements within 'billing/page.tsx' are enhanced for better user experience.
Added a 'Subscription Cancelled' alert in the billing component to improve visibility of subscription status. Also, removed an unnecessary check for target_account_id in billing-event-handler service as it lead to early exits. Fixed a typo in stripe-webhook-handler service for better consistency in naming conventions.
Code for billing process was refactored in end-to-end tests for clean code and better structure. In the described tests, related codes and classes have been moved to a new class named BillingPageObject. All corresponding calls were updated accordingly.
Changed the billing provider in the `.env.development` file from Stripe to Lemon Squeezy. This requires adaptations at many levels: at the web app to load Lemon Squeezy's script in the checkout process, at the billing gateway to handle Lemon Squeezy calls, and in the database to reflect the current billing provider. The checkout process is now done using Lemon Squeezy Sessions and its billing strategy was adjusted accordingly. Billing-related components and services were also updated.
