fix(blog): preserve sticker aspect ratio in conversation snippets

The avatar slot had no explicit width, so the flex layout shrunk it
below 64px and the base img max-width:100% rule then constrained the
sticker to that narrower box. Pin the container to 64×64 with
shrink-0, set max-w-none and object-contain on the img so non-square
source stickers render at their natural aspect ratio.
