Fix Performer Popover Placement in Scene Scrape Results

[Stash-KennyG]

Summary

Addresses cutoff performer pop-over in scraper UI where the performer card extended to the top of the page and was largely cutoff.

Why

In Scene Tagger scrape results, performer hover cards were appearing above chips in a way that clipped content in most layouts.
This change gives the performer chips in this specific flow an explicit bottom placement request to improve readability and reduce visual overlap.

Files Changed

• ui/v2.5/src/components/Shared/ScrapeDialog/ScrapedObjectsRow.tsx
  • Add hoverPlacementLabel="bottom" to PerformerSelect in ScrapedPerformersRow.

Risk / Notes

• Very low risk: one prop added in one usage site.
• No API/schema/data changes.
• No backend changes.
