feat: game importance factor in hype scoring

Adds calculate_game_importance() that boosts Priority for high-stakes
regular-season matchups based on season progress (sharp ramp after game
55), playoff bubble proximity (wildcard rank ~17-19 = max relevance),
and divisional/conference rivalry (1.4x/1.2x multipliers). Max bonus
150 pts applied to both LIVE and PRE games; playoff and FINAL games
are unaffected. Extends standings schema with division, conference,
games_played, and wildcard_sequence fields fetched from the NHL API.
