scoreboard: respect opt-score as tiebreaker in row ordering

Add opt-score comparison to Scoreboard::scoreCompare().
When ‘Use optimisation score as score-tiebreaker’ is enabled, the
list is now sorted by:

  1. points
  2. totalOptScore (max or min, per contest setting)
  3. total runtime / total time
  4. solve-times sequence

Fixes the discrepancy where the UI still ranked teams by first-AC
time even though opt-score decided the official rank.
Supports both “maximize” (desc) and “minimize” (asc) modes.
