feat(live): esecuzione REALE su Deribit testnet (shadow) per i 6 fade sui lineari USDC

- ExecutionClient: notional->amount (lineare USDC + inverse), open/close_amount
  reduce-only, verifica sul trade (order_id), fee reali lette dai trades[]
- CerberoClient: place_order market + reduce_only, get_trade_history
- StrategyWorker: shadow (REAL_OPEN/REAL_CLOSE accanto al sim), ledger reale
  parallelo persistito, confronto slippage/fee sim-vs-reale
- runner+portfolios.yml: config execution (6 fade MR01/MR02/MR07 x BTC/ETH su
  BTC_USDC/ETH_USDC-PERPETUAL), capitale 2000
- smoke: live_exec_smoke (layer) + live_shadow_smoke (catena worker), provati su testnet

"""Esecuzione REALE su Deribit (testnet) con verifica post-ordine e fee reali.
Flusso per ogni ordine:
1. converte il notional (USD) in `amount` Deribit, arrotondato allo step del
contratto (BTC-PERPETUAL step $10, ETH-PERPETUAL step $1) e clampato al minimo;
2. piazza un market order REALE via Cerbero → Deribit private/buy|sell;
3. RIVERIFICA su Deribit: rilegge get_positions (la posizione esiste con la size
giusta?) e get_trade_history (ritrova il fill per order_id) — non si fida della
sola risposta dell'ordine;
4. estrae la FEE REALE dai trades[] del fill (per i perp inverse la fee e' nel
coin di settlement: BTC/ETH → la convertiamo anche in USD col prezzo di fill).
NB perp inverse Deribit: `amount` e la dimensione posizione sono in USD notional;
la fee dei trade e' denominata nel base-coin (BTC/ETH).
