Subject: [PATCH] fix: show relevance badge for single-source citations
 (#29647)

A response with exactly one citation never showed its relevance badge, even though the source carried a perfectly valid score. Adding a second citation made the badge appear for that same source, so the score looked like it came and went at random.

calculateShowRelevance hides relevance when a result set mixes distance metrics (cosine in -1..1 next to unbounded L2), since those numbers are not comparable. With a single distance that check degenerates: distances.length - 1 is 0, so the "all but one are out of range" clause matches whatever the value is, and the score is hidden. A lone distance cannot be a mix of two metrics, so it now returns before the outlier check runs.

Sets of two or more distances behave exactly as before, mixed-metric sets are still suppressed.

Fixes #29646
