fix(news): count lead cards in degradation check, add draft dry-run script

Trying to push a WeChat draft locally surfaced two problems.

isNewsMorningContentDegraded matched cards with `class="card(?:\s|")`, which
never matches news002's `class="lead-card"`. Headline cards were therefore
invisible to the check, so a healthy news002 page could be flagged as degraded
and regenerated. Count cards through the shared extractor instead, which
handles card, lead-card and highlight-box alike.

Add scripts/dryrun-news-morning-draft.mjs to run a page through the dedup gate,
degradation check, inline conversion and footer layout without calling the
WeChat API, since local IPs are not in the official account whitelist
(errcode 40164) and a real push would write into the production draft box.
