fix: silently ignore PeerTube View activities in ActivityPub inbox

PeerTube broadcasts non-standard View (WatchAction) activities to all
followers on every video watch. Fedify has no handler for this type,
causing noisy "Unsupported activity type" errors in the federation log.

Adds a no-op .on(View, ...) handler at the end of the inbox listener
chain via the existing patch script mechanism.
