feat(service): P6.3 route REST + approve/deny → execute to sandbox

RouteService (createBinding/listBindings/simulate/listDecisions/approve/deny/
execute/flushDigest); approve REVIEW→ALLOW + route.approved event → execute via
P5 OutboundService (sandbox, idempotent per decision); deny never executes.
7 route endpoints; PORTAL adapter registered. 5 route tests green.
