* Fix standings page team icons to use selected team avatar
The full standings page was not passing avatar data (logoUrl, flagConfig,
avatarType, ownerAvatarData) to StandingsPreview entries, so all teams
showed the default initials fallback instead of their chosen avatar.
Fetches the avatar columns from the teams table in the loader, resolves
owner avatar data for teams using the owner avatar type, and threads
all avatar fields through formattedStandings into previewEntries.

* 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).

* Fix StandingsPreview test ambiguous text query for team names
FlagSvg renders a <title> element with the team name for accessibility,
so getByText("Team Alpha") matched two elements. Scope the query to the
<p> element to target only the visible team name display.
