fix: correct NHL API situation structure for power play detection

The NHL API nests situationDescriptions under situation.homeTeam /
situation.awayTeam, not at the top level. The old flat-structure
lookup always returned an empty list, silently breaking both the
PP indicator on the frontend and the PP bonus in the hype score.
Updated get_power_play_info, the _priority_components PP check,
and all test fixtures to match the real API shape.
