Discount Codes for Direct Bookings Need More Parameters/Options for Restrictions

We need more parameters/restriction options for discount codes for direct bookings, specifically the option to choose blackout dates within the booking window and maximum stay length caps.

Examples: If a discount code is valid from February 2026 to February 2027, we need the option to choose blackout dates/dates not available within that window.

We also need to be able to say “this code is good for 3 nights maximum.” We have the minimum stay option but we need the max as well.
