DevToolsEmptyState class

A centered icon, message and optional hint shown when a DevTools tab has nothing to show yet.

Use it in a custom tab so its empty screen looks like the built-in ones.

Example:

if (events.isEmpty) {
  return const DevToolsEmptyState(
    icon: LucideIcons.wifiOff,
    message: 'No socket messages yet',
    hint: 'Connect a socket to see messages here.',
  );
}
