feat: wire GBKMediaUploadProcessor into the GutenbergKit editor

Sets the media upload delegate on GutenbergView so device media picked
in the experimental block editor is processed per the app's media
settings before upload. The fragment stores and forwards the delegate
following the existing setNetworkRequestListener pattern (GutenbergView
tolerates assignment before or after page load), and the activity
constructs the processor with its SiteModel and injected wrappers.

If GutenbergKit's upload server fails to start, uploads degrade to the
existing WebView path unchanged.
