Kevin signals never placed orders: the executor sized only from
sentiment_context["current_price"] (None for Kevin) so qty=0, and orders
were always built SIMPLE (stop/take pcts ignored).
- TradeSignal gains `current_price`; the bridge now sets it on publish
- risk_manager honors `target_dollars` directly (no strength re-scale) and
resolves price from current_price then sentiment_context
- executor builds BRACKET orders for LONG entries carrying stop/take pcts;
EXIT/SELL signals stay SIMPLE (the bridge sets pcts even on exits)

all injected. Master kill-switch (kevin_enable_trading=false) routes to
audit-only path. Cursor advances ONLY after XADD succeeds (race fix).
Concrete collaborators wired in subsequent tasks.
Also extends TradeSignal + SignalDirection.EXIT with the optional
fields Kevin paths need (strategy_id, target_dollars, stop_loss_pct,
take_profit_pct).
