Show Security Deposit Due Date on Direct Booking Invoices

Currently, when using the "Hold" security deposit strategy in Direct Booking listings, the invoice displays the due date of the second payment instead of the actual security deposit hold date. This creates confusion for hosts because the invoice does not reflect the deposit timing configured in the listing settings (e.g., 2 days before check-in).

Even though the system correctly applies the deposit rule during the reservation process, the invoice does not show the deposit due date, which makes it difficult for hosts and guests to clearly understand when the deposit will be held.

Expected behavior
Invoices should display the correct security deposit hold date based on the listing configuration (for example: "Security deposit will be held 2 days before check-in").

Impact
Improves transparency for hosts and guests and prevents support tickets caused by mismatched payment information between listing settings and invoice documents.
