Screenshots: Manual payments walkthrough (6 placeholders)

[superdav42]

For #64.

Problem

docs/user-guide/payment-gateways/manual-payments.md references 6 distinct concepts but each is one of two recycled images. Lines 20–28 use settings-payment-gateways.png for the manual-gateway configuration row and two frontend states; lines 34–42 use payments-list.png for the payments-list, payment-detail, and status-change screens.

Captures required

Setup on wordpress.local:8080: enable the Manual gateway, fill in a short payment-instructions message, then register a customer who chooses Manual at checkout so there is at least one Pending payment to show.
