Retrieves all order line items associated with the specified order ID and initiates billing for each one
using the provided ReadyForBillingDate. The billing records created depend on the price type and
billing frequency of each order line item:

• One-Time Products – If both the price type and billing frequency are set to One-Time, a single billing schedule record is created.
• Recurring Products – If the price type is Recurring and the billing frequency is Monthly, Quarterly, or Yearly, a cascade of billing schedule records is created based on the selling term.

If the number of order line items exceeds the configured threshold, the operation automatically switches to asynchronous processing regardless of the isAsync flag.

Upon completion, the ReadyForBillingDate on the order is updated based on the overall success or failure of the billing initiation.
