render markdown hard breaks and image placeholders (T-379)

Browse Source 
Both node types fell through the inline-span switch to an empty
textContent span: words on either side of a hard break glued
together, and images vanished with no trace. A br now emits a
newline; an img renders a muted italic "[image: alt]" placeholder
(falling back to the src) — no inline network loading in the owned
renderer; live-pane images keep going through clide image show.
