pose-aware chat bubble behind a Pose Portraits setting

Reads org.gamecult.pose from event content for senders that are known
Minds; unknown or missing labels fall back to neutral. Portrait sits
beside the bubble on wide screens and stacks above it on phones.
84 downscaled webp portraits (7 Minds x 12 poses, ~415 KB).
