feat(live): executor a 2 gambe per i pairs (PairsExecutionClient, shadow) — pronto, spento

Browse Source 
PairsExecutionClient (compone ExecutionClient): open_pair (2 market long A/short B,
verifica per-gamba, LEG-RISK unwind se una sola filla), close_pair (2 reduce-only via
close_amount, MAI close_position), register_contract (fetch spec USDC). Spec LTC/ADA/SOL
aggiunti. PairsWorker: ledger reale shadow a 2 gambe resume-safe (_real_open_pair/
_real_close_pair, PnL per gamba dir A=+d/B=-d, doppio arrotondamento riportato). Runner:
pairs_executor gated su execution.pairs_enabled (false di default).

Validazione: test 92/92 (open/close, leg-risk unwind, resume) + smoke testnet
end-to-end (open 2 gambe verificate, close reduce-only, PnL reale -0.039 vs sim -0.036,
conto flat). Smoke ora aborta se ci sono posizioni di produzione + usa solo close_amount.

NB incidente testnet documentato (diario): pulizia manuale con close_position ha flattato
le quote shadow dei fade sul conto condiviso -> auto-riconciliazione al prossimo close.
Lezione: mai close_position su strumenti condivisi.

pairs_enabled resta FALSE: accendere con finestra a conto flat + osservazione.
