refactor(revenue): drop standalone QR block and align promotion card with reference

The 推广收益 detail card no longer renders the QR code as its own row. The
card becomes a fixed-label info list: 推广链接 [Url][复制链接][推广海报] /
佣金比例 / 累计佣金 / 返佣详解, mirroring the reference theme's 推广中心 card.

- profile-revenue.php: QR row removed; poster button moved into the link row and
  gated server-side on the poster switch; copy label now 复制链接; 推广人数 row
  dropped; 返佣详解 heading reads the existing pay_rebate_text_details_title;
  dead $vip_ratios, aksrt-revenue-page class and data-min-amount removed
- new affiliate-poster-modal.php: poster previews in a modal before download
  (reuses .uc-modal + single-render guard), since the QR now only exists inside
  the poster
- credits.js: renderAffiliateQr and its call deleted, along with the dead
  [data-affiliate-payers] lookup and the inline ch-width hack; initAffiliatePoster
  builds the poster into the modal stage and reveals 保存海报
- PaymentRuntime: expose affiliate details_title
- user-center.js: remove never-defined AKSRTRevenueCenterInit guards (2 sites)
- CSS: revenue-earnings.css pruned to live rules plus the new link-row grid and
  poster stage styles; routes/user-center/revenue.css pruned to its only
  definitions; dead leaves routes/revenue.css and routes/commerce.css deleted and
  dequeued from the user-center part list
- tests: referral-qr-contract test 2 rewritten for the QR-free card, link row and
  poster modal; post-visual-contract leaf list updated with regression guards

qrcode.min.js stays enqueued — buildPosterCanvas still draws the QR inside the
poster. Net -833 lines.
