fix: show source URL in search input on ranking autocomplete selection

- selectItem() now sets the visible input to source_url (not the title), so the user can see and copy the link before scraping
- Keyboard navigation (ArrowUp/Down) also previews the URL in the input
- Added URL hint line inside each dropdown item showing the full source_url
- Genres included in search haystack (was missing before)
- Deduplicated filter logic into filterRanking() helper
- Raised max results from 8 to 10
