fix: resolve example errors and Column overflow

- Fix ListTile leading: replace rate-limited network image with a
  local colored box + icon (no more HTTP 429 errors)
- Fix Column RenderFlex overflow: replace AspectRatio(1.0) with
  ConstrainedBox(minHeight = width) so the alert box is at least
  square but grows to fit content when title + subtitle + icon
  would otherwise overflow
