feat: expose the validation banner for custom editors (1.2.2)

ValidationInspectorBanner is a [CustomEditor(typeof(MonoBehaviour), true)]
fallback, so any component with its own CustomEditor silently lost the orange
"needs setup" banner - it kept the hierarchy dot, field tint and console log,
but the banner itself was unreachable private code.

Move the drawing into ValidationUi.DrawIssuesBanner(Component) so a custom
editor can call it in one line, and reduce ValidationInspectorBanner to a
delegation. No behaviour change for components using the default inspector.
