Add leasing as a payment option

Introduce a built-in lease payment calculation feature in Salesbuildr, allowing users to offer customers flexible options for leasing or purchasing quoted products. Users can present multiple lease terms, such as 24-month or 36-month leases. Lease payments would dynamically recalculate based on changes in the quote total.

Key Requirements:

Lease Payment Options: Provide multiple lease choices (e.g., 24-month, 36-month) with monthly payments and total cost details.

Real-Time Recalculation: Lease payments automatically update with any changes to the quote.

Support for Multiple Leasing Companies: Allow input of leasing rate factors from different companies.

User-Friendly Interface: Enable easy management of leasing options.

Benefits:

Enhances sales flexibility and transparency.
Boosts efficiency by automating recalculations.
