The card below the writing surface only offered cover and scheduling, so
paid content could only be reached through the bottom bar's 发布 button.
- The card gains a 付费内容 row (rendered only with canPay): a toggle bound
to draft.pay.enabled, a status line that reflects whether resources were
added, and a 配置价格与付费资源 link.
- Turning the toggle on opens the publish drawer and scrolls it to the pay
section, so pricing is the next thing the author sees. Entering from the
bottom bar keeps the drawer at the top.
