[Bug] Mobile story page — widgets buried below full story content

[realproject7]

Bug

PR #111 uses a two-column grid that stacks to single column on mobile. The sidebar widgets (trading, price chart, ratings, donations) appear below ALL story content on mobile. Users must scroll past the entire story to access them.

Fix: On mobile, add a sticky "Trade / Rate" action bar or reorder key widgets (e.g., trading widget) above story content using Tailwind order-first lg:order-none. Alternatively, add anchor links at the top that jump to the widget section.

Checklist:

• Mobile users can access trading/rating widgets without scrolling past full story
• Desktop layout unchanged
• npm run lint and npm run typecheck pass
