cookiebanner: detect service workers and Cache Storage buckets

A registered service worker is a URL-shaped artifact (origin+path of
the worker script), so it goes in tracker_resources as a new
SERVICE_WORKER resource type. A Cache Storage bucket is an opaque
named string with no URL, so it goes in detected_trackers as a new
CACHE_STORAGE tracker type.

Frontend:
  - StorageDetector wraps caches.open() and enumerates caches.keys()
    on start to surface pre-existing buckets that pre-date the SDK
    load (service workers commonly populate caches eagerly on
    install).
  - ThirdPartyDetector wraps navigator.serviceWorker.register() and
    enumerates getRegistrations() on start.

Both wrappers degrade silently on insecure contexts where these APIs
are unavailable.
