Add dcy-004 Discovery (draft): portfolio-hub ledger integration

Browse Source 
Record fills to the portfolio-hub ledger (orbit post_ledger_trade pattern)
so external accounting/positions reflect trades. The slot already carries
portfolio_id but nothing consumes it; this closes a deferral not previously
made explicit in dcy-003. Scope: LedgerPort + portfolio-hub adapter + stub,
record on buy/sell fill, execution_id idempotency, failure retry/hold;
out of scope: non-trade transactions, asset sync, reconciliation. OQ-1
(asset_id source), OQ-2 (durability), OQ-3 (exec data source) left for
confirm-discovery; handoff held.
