cookiebanner: broaden resource detection via PerformanceObserver

ThirdPartyDetector previously only saw <script src> and <iframe src>
because it scanned the DOM and watched mutations. Add a single
PerformanceObserver({type:'resource', buffered:true}) that picks up
everything the browser actually loaded:

  - tracking pixels (<img>, <picture>, srcset)
  - cross-origin stylesheets and web fonts
  - fetch / XHR / sendBeacon / ping calls (SDK call-homes)
  - video, audio, embed, object media

initiatorType is mapped to six new tracker_resource_type enum values
(IMAGE, STYLESHEET, FONT, BEACON, FETCH, MEDIA) and the existing
upsert path in tracker_resources picks them up unchanged.

Closes a real gap with headless cookie scanners: most SDKs phone home
via beacons after their script is gone, and the DOM scan never saw it.
