refactor(preview): unified message notification component
Replace ad-hoc #static-notice with reusable .message system:
- .message — base notification bar, spans full width below navbar
- .message-warn — amber/yellow warning (static mode notice)
- .message-error — red error (missing rendered.js, dev disconnect)
- showMessage(html, type) / clearMessages() helpers
- Messages stack vertically in #messages container
- Static notice auto-shown on page load; cleared on dev ws connect
- Dev reconnect/disconnect events shown as error messages
