PINK Phase 0: FET -$5,990 fix batch — leverage-free PnL, true fill prices, reconcile baseline anchors

Defects fix (FET -$5,990 replay, 2026-06-11):
- realized_pnl() and mark_price(): PnL = qty × Δprice, side-signed; no ×leverage inflation (was 3× every leg).
- BingX MARKET fill events carry true fill price (avgPrice/lastFillPrice), never the order's nominal price (protective bound ±20-25% from mark, poisoned PnL to -$5,990 on a +$164 round-trip).
- Fill routing by ORDER IDENTITY first, FSM state second — late entry-remainder fills during EXIT_WORKING no longer misclassify as exits.
- Entry basis = VWAP across entry fills, not last fill price.
- reconcile_from_slots / restore_state: re-anchor _last_settled_pnl / _slot_was_closed to adopted slot state (cross-restart double-book of carried PnL).
- ACCOUNT_UPDATE with wallet_balance=0 dropped (margin-only frames no longer zero e_available_margin).
- Foreign-fill skip on shared VST account (PRODGREEN collision filter).
- exec_router TTL: entry-requote venue-truth gate (recent own fill + live exchange position probes prevent double-entry).
- bingx_direct: openOrders fetched BEFORE positions (sequential ordering prevents dangerous tear → double-entries).
- Dual-leverage translation via map_internal_conviction_to_exchange_leverage() (strategy conviction → integer at-exchange leverage, bankers rounding).
- BLUE-parity alpha components wired: asset picker (IRP universe ranking) + alpha sizer (cubic-convex dynamic leverage, 0.5-8.0 range).
- ch_writer: date_time_input_format=best_effort on insert URLs; flush error logging at WARNING with counter.
- blue_parity.price_of(): hyphen-tolerant fallback (FET-USDT → FETUSDT).
- Fill test updated to incremental filled_size semantics (BingX WS lastFilledQty).
- Env-override base URLs, supervisord autorestart, per-asset DC histories, single-slot invariant, fill-attribution filter.
