Current PRUVIQ paper-trading portfolio state.

Reads the cycle file the daily paper-trading job writes. No simulation runs inside this request — it's a JSON read of the most recent state.

Query: cycle: optional cycle id (e.g. 1). Defaults to the latest.

Response shape (when a cycle exists): { "cycle_id": 1, "cycle_status": "active", "cycle_day": 14, "cycle_length_days": 30, "start_date": "2026-04-16", "starting_capital": 1000.0, "current_equity": 1247.50, "total_return_pct": 24.75, "yesterday_pnl": 21.30, "open_positions": [...], "closed_positions": [...], # most recent 20 "history": [{"date", "equity", "open_count", "closed_count"}, ...], ... }

When no cycle exists, returns 404 — callers should treat that as "not initialized yet" rather than "feature off".
