fix(revenue): align detail card, poster modal and copy feedback with reference

- detail-tab 累计佣金 row now shows 累计 + 已提现 (was 累计/可提现/已提现)
- rebuild poster canvas to match reference layout (768×1168, top banner,
  date overlay, blue title bar, bottom bordered box with QR + link)
- copy-link feedback moves from inline text to a toast (notyf), matching
  the reference; drop the now-unused data-affiliate-feedback element
