"""Report orario PORT06 -> Telegram.

Legge lo stato persistito del paper trader a portafoglio (data/portfolio_paper/*/ +
data/portfolios/PORT06/status.json) e invia su Telegram:
  1) trade CHIUSI: positivi/negativi (netto fee) con breakdown per motivo e PnL;
  2) trade IN CORSO (posizioni aperte);
  3) PnL realizzato totale + equity mark-to-market.

Eseguibile standalone (es. da cron orario):
    cd /opt/docker/PythagorasGoal && uv run python scripts/portfolios/hourly_report.py

Carica .env da solo (cron non eredita l'env del container). Legge file world-readable
scritti dal container; non tocca lo stato del trader.
