Test-First Scrape Comparison Page

What Was Built

Test-first scrape feature: picks a recent item from a source, scrapes it on-demand via ItemScraper, and shows a comparison page with feed vs scraped word count. Button on source show page triggers the test, result replaces via Turbo Stream.

7f34b2c	feat(scrape-test): add Test Scrape button to source show page

Tasks Completed

1. Create ScrapeTestsController -- Controller with create action, picks test item, scrapes it, computes improvement percentage.
2. Add route for scrape tests -- resource :scrape_test, only: :create nested under sources.
3. Create scrape test result partial -- Grid comparison view with feed vs scraped word counts and improvement indicator.
4. Add Test Scrape button to source show page -- Button visible when scraping disabled, triggers POST via Turbo.
