Replace ranking Scrape button with two-click card interaction

- Remove Scrape form/button and Source text link from non-local ranking cards
- First click on a card highlights it amber and shows 'Click again to scrape' hint
- Second click POSTs to /ui/scrape/book and replaces card with polling status badge
- Pending state auto-cancels after 3 s or when clicking outside
- Source icon (external link SVG) retained but dimmed; stops click propagation
