feat(extraction): read headless mode from config instead of hardcoding

Add headless field to extraction config schema (default: true).
Extractor handler now reads globalConfig.extraction.headless instead
of hardcoding true. Users can set headless: false in config.yaml
to show the browser window during extraction for debugging.
