web: fix mobile nav stuck-open on rejoin + paste-chip code fence

Browse Source 
useViewport re-syncs the snapshot on pageshow/visibilitychange/resize/orientationchange — iOS reported a stale width on backgrounded-tab restore, leaving isMobile=false so the sidebar rendered as a permanent column with no close affordance. flattenToMessage now inserts pasted-text chips verbatim instead of wrapping them in a triple-backtick fence.
