Adds a new "Цифровой бейдж" tab for preparing 240×240 PNG circles for
round digital displays. Photos come from device upload or the existing
Flickr selection. Each photo can be drag-cropped and zoomed (mouse,
wheel, or pinch on touch), have a yellow price tag (arc band or
rectangular plate, with auto thousands separator and ₽), and a curved
nickname signature — which auto-moves to the top of the circle when a
price tag occupies the bottom. Saves are routed through the Web Share
API on phones so the badge lands in the iOS/Android Photos app
directly; history of saved badges is kept under data/badges/. Default
nickname is stored in Settings.
