vc=32 fix: drop SearchItem.uploader_avatar — not on StreamInfoItem

I confused StreamInfo (the big single-video struct, has
uploader_avatars: ImageSet) with StreamInfoItem (the card struct used
in search results / channel video lists / related streams — no
uploader_avatars field). cargoBuildHost caught it: E0609 no field
`uploader_avatars`.

Drop the field from SearchItem (and from the Kotlin construction
sites). For the subs feed and "more from this channel" we already
use the channel-level avatar from ChannelInfo.avatar, which is the
right granularity anyway (every video from one channel shares one
avatar). Per-card uploader avatars on search/related stay null until
strawcore-core extracts them on StreamInfoItem too.
