chore(monitor): cron giornaliero (refresh dati + avanza paper) + cleanup crontab/orfano

scripts/cron_daily.sh: rebuild_history BTC/ETH + fetch_hyperliquid (52 alt) + fetch_dvol +
paper_portfolio, ogni giorno 00:30 UTC -> tiene fresco il dato che il dashboard legge e avanza
il paper forward. fetch_hyperliquid END ora DINAMICO (oggi) per il refresh.

Cleanup: rimosso container orfano pythagoras-portfolio (vecchio runner pre-reset, exited);
crontab ripulito dai 4 job rotti del micro-test mainnet (hourly_report/drift/reconcile/
ledger_vs_backtest -> script archiviati in Old/), backup in logs/crontab.pre-reset.bak.
