feat: overhaul hype scoring algorithm

- Period base: playoff OT escalates indefinitely (P4=600, P5=750…),
  reg season P4=5-min OT (600), P5=shootout (700)
- Time priority range increased (max ~300 vs old ~120), calibrated
  to period length so 5-min reg season OT reads correctly
- Matchup multiplier inverted: higher period = less weight (any OT
  is exciting regardless of teams)
- Replace unconditional score_total with closeness bonus: rewards
  tight games regardless of goal volume (5-4 == 1-0 at same diff)
- Power play bonus: 30 (P1/P2) → 50/100/150 (P3 by time) → 200 (OT)
- Comeback bonus: one-time pulse (+50/75/100 by period) when trailing
  team scores to within 2 goals; keyed on team names, clears after
  firing, skips intermission
