v1.143.5 — A washout is billed like any other activity

An activity set not to email the customer, like Day 1 Washout, still carries a price: payment links, receipts and invoices always go and list it.

Payment links and receipts always go — even when the only thing on a booking is a washout, the customer gets the payment request, the payment and refund receipts and the invoice.
The washout is its own line — under the activity's own name and price, so the total in the email is exactly what the payment page charges.
Reminders never ask for less — on a booking with a washout and other activities, the balance and trip reminders, the itinerary and the cancellation email count the washout's money and list it, so the amount always matches the payment page.
Everything else stays quiet — when a washout is all that's booked, confirmations, reminders, form and waiver requests, review requests, cancellations and texts about it still aren't sent.
