Parse and expose SessionStatus from the official live feed, treating Started/Resumed as active and terminal or missing statuses as inactive archive candidates.
Keep /api/v1/live/state and SSE snapshot data reserved for active sessions while exposing memory-only last_snapshot, last_positions, and last_snapshot_at for the explicit Live tab archive view.
Replace the static weekend band with a three-state hero (live, upcoming,
between weekends) driven by heroState() and existing page queries. Between-weekend
podium uses the existing race-hub endpoint for the last ingested race session
since championship hub does not expose finish positions.
