Each condition kind (ROUTE_METRIC, EXCHANGE_MATCH, AGENT_STATE,
DEPLOYMENT_STATE, LOG_PATTERN, JVM_METRIC) renders its own payload-shape
form. Changing the kind resets the condition payload to {kind, scope} so
stale fields from a previous kind don't leak into the save request.
Deviation: DS Select uses native event-based onChange. Plan draft showed
a value-based signature (onChange(v) => ...).
