[PF] Remove legacy image-rendering from Avatar

[azebich]

Description

Removes the [image-rendering:-webkit-optimize-contrast] arbitrary class from ImageAvatar.

It was a hack for a long-fixed Chrome bug with blurry downscaled images. Chrome now aliases -webkit-optimize-contrast to crisp-edges, which forces low-quality (nearest-neighbor-style) scaling — the opposite of its original intent. With it removed, avatar photos use the browser's default high-quality resampling.

Jest snapshots for AccountSelect and PageTopBarMenu updated (they embed the avatar class list).

How to test

• Temploy
• Open Avatar stories with photo sources — downscaled photos should look slightly smoother, no other changes
• Review the Happo report: only avatar-bearing snapshots re-render, with minor edge/sharpness diffs on the photos (intended)
