* feat: add BillingCacheService with 1-hour TTL for team subscription data - Create BillingCacheService following CalendarsCacheService pattern - Use teamId-based cache keys with 1-hour TTL (3,600,000 ms) - Integrate caching into getBillingData method in BillingService - Add cache invalidation to all webhook handlers: - handleStripeSubscriptionDeleted - handleStripePaymentSuccess - handleStripePaymentFailed - handleStripePaymentPastDue - handleStripeCheckoutEvents - Add cache invalidation to cancelTeamSubscription method - Add RedisModule import to billing module - Add BillingCacheService to billing module providers - Add findTeamByPlatformBillingId method to OrganizationsRepository for cache invalidation Co-Authored-By: morgan@cal.com <morgan@cal.com> * refactor: implement BillingServiceCachingProxy pattern - Extract IBillingService interface with all public methods - Create BillingServiceCachingProxy that implements caching logic - Remove all caching logic from original BillingService - Simplify cache invalidation using billing.id = team.id - Update module to use proxy with proper dependency injection - Update controller to inject proxy interface - Remove unused BillingService import from controller This follows the proxy pattern requested in PR feedback, separating caching concerns from core billing logic for better maintainability.
