Subject: [PATCH] feat(chat): move scope chip to header, consolidate voice
 controls into input bar

Phase B of chat view refinement. Bumps chat reading column to 1200px,
lifts the RAG scope chip out of the footer and into the ChatView header
(next to the title), and collapses the listen toggle / volume slider /
stop-playback buttons into a single speaker popover on the input bar.
Listen mode + TTS are now available in briefing and workspace chats too,
since the controls live on the shared ChatInputBar.
