feat(live-chat): surface stream clips in the profile gallery tab

Clips are authored by viewers but carry a `p` tag identifying the
stream host, so they naturally belong on the host's profile. Extend
the profile media subscription with `{kinds:[1313], #p:[pubkey]}`,
accept LiveActivitiesClipEvent in UserProfileGalleryFeedFilter when
the clip references a stream hosted by this user, and render the clip's
`r`-tag URL as a MediaUrlVideo tile in GalleryThumbnail.

Also plug LiveActivitiesClipEvent into NoteCompose via the existing
RenderChatClip so tapping a clip tile opens a working thread view
instead of an empty one.
