Get all map scores

Retrieve every map score for a match plus a series summary. Returns the full unpaginated list of map scores (no cursor or limit) and a seriesScore counting map wins per side, computed only from CONFIRMED maps and awarding a map to the side with the strictly higher score (equal scores count for neither). Each score's scoreStatus is CONFIRMED or PENDING; submittedBy, confirmedBy, and createdAt may be null. Screenshot URLs are suppressed (empty array) for any score whose API-uploaded image has not passed content moderation. Requires one of matches.user_matches:read, matches.team_matches:read, or matches.org_matches:read. The caller must be an active member of one of the match's two teams; non-participants receive 403, unless they hold a TeamBattles staff role, which can read any match's scores.
