IGDB: add DOS-only search, gameplay videos + screenshot support

- Search now filters to DOS platform only (platform ID 13)
- New fetchVideos() queries IGDB game_videos endpoint for YouTube IDs
- New fetchScreenshots() queries IGDB screenshots endpoint for images
- autoScrape and applyIgdbId both fetch videos + screenshots after match
- Upload auto-save also triggers when videos/screenshots found
- GameDetail: embed first YouTube video + scrollable screenshot gallery
- Handles missing media gracefully (section hidden entirely if neither exists)
