feat: overhaul hype score algorithm with 9 hockey-driven improvements

- Empty net detection: pulled goalie triggers +150-250 bonus, stacks with PP
- Playoff series importance: Game 7 Cup Final = 200, elimination games scale
  by round; fallback of 100 when series data unavailable
- Period-aware score differential: 2-goal deficit penalty DECREASES in final
  2 min of P3 (goalie-pull zone), 3+ goal games get harsher penalties late
- Persistent comeback narrative: tracks max deficit, sustained bonus for 2+
  goal recoveries instead of one-shot spike (0-3 to 3-3 = 150 persistent)
- Shootout special handling: flat base 550 with no time component; ranks below
  dramatic close P3 games (skills competition, not hockey)
- Multi-man advantage: parses situationCode for 5v3/4v3, applies 1.6x PP mult
- Non-linear time priority: elapsed^1.5 curve weights final minutes more
- Matchup multiplier rebalance: P1/P2 from 2.0/1.65 to 1.5, tiebreaker not
  dominant factor
- Frontend gauge max raised from 700 to 1000 with adjusted color thresholds
