Subject: [PATCH] feat(buzz): fix channel/forum type on the create screen from
 the caller
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The create screen no longer shows a "Forum channel" toggle — the type is decided
by the community's per-section "+" (Channels vs Forums) and a Buzz channel's
channel_type isn't editable anyway (the relay's 9002 has no such key). The screen
loads with the fixed isForum parameter and creates the right type; its top-bar
title reads "New forum" when isForum, "New channel" otherwise (on Buzz).
