Subject: [PATCH] Add StandingsPreview component tests covering avatar
 rendering

Tests were missing for the StandingsPreview component, which is the
component that actually renders team avatars on the full standings page.
Covers uploaded image, flag SVG, owner avatar inheritance, and the
generated-flag fallback, plus basic content rendering (team names,
owner names, points, description, full standings link).
