feat: rank projects by balanced score in ranking dashboard

Initial ranking order, advancement cutoff line, and per-row "advancing"
highlight now all use the juror-balanced (z-score corrected) average,
falling back to the raw avgGlobalScore when no balanced score exists.
The init effect waits for evalScores so the sort has the data it needs.

Admin drag-reorders still take precedence — saved reorders override the
default sort exactly as before.
