Add Klarna Payment Option + UI Update on Booking Page

I’d love to see Klarna added as a payment method in the next version of RepairPlugin. This would give customers more flexibility, especially for higher-cost repairs. Additionally, it would be great to update the booking page UI where the price is displayed. I suggest adding a line of text next to the price: “Or $15/mo with [Klarna logo]” (Or dynamically adjust the monthly price based on the total.) This small change can make a big impact by letting customers immediately know they have the option to split the payment, which might reduce hesitation due to price. Thanks for all the great work!
