Include kind 1111 comments in feeds and profile 'Posts & replies' tab

Add kind 1111 to EXTRA_KINDS tied to feedIncludePosts so comments
appear in all feeds (follows, global, communities) and profile feeds.
Explicitly exclude kind 1111 from profile 'Posts' tab since they are
always replies. Treat kind 1111 like kind 1 in streaming filter so
reply/search/media filtering applies consistently.
