Add scraper run history table to Scraper Management page

Fetches last 30 scrape events from /api/admin/scraper/history and
displays them in a table with time, status, trigger type, duration,
units processed, prices inserted, and dry run columns. History
refreshes on page load, manual refresh, and after triggering a scrape.
