Retrieve a list of payment links with optional filtering and sorting capabilities.

This endpoint allows you to search through payment links using various criteria such as:

• Business unit identifier
• Status (active, used, cancelled)
• Amount ranges
• Customer information
• Creation and expiration date ranges
• Associated booking IDs or booking references (booking.booking_reference)

Results can be sorted by creation date, expiration date, amount, or status.

Expand Parameter: Use the expand parameter to include full object details instead of just references:

• expand: ["booking"] - Returns shallow booking objects (core booking details without components or payment references) instead of just booking IDs
