Get Weibo user followers

Returns the Weibo followers (fans) list of the specified user, returning follower profiles (nickname, avatar, bio, followers count, latest post, etc.). Send uid (User ID); optional page. This endpoint uses the Weibo mobile (m.weibo.cn) H5 API and relies on the server-side cached logged-in cookie; an expired cookie results in an error. Weibo limits the pagination depth of the followers list (in practice users becomes an empty array and next_page becomes 0 after roughly 1000 records).
