Phase 0: Foundation & Credit System - Initial implementation
- Updated CREDIT_COSTS constants to Phase 0 format with new operations - Enhanced CreditService with get_credit_cost() method and operation_type support - Created AccountModuleSettings model for module enable/disable functionality - Added AccountModuleSettingsSerializer and ViewSet - Registered module settings API endpoint: /api/v1/system/settings/account-modules/ - Maintained backward compatibility with existing credit system
