BankEmptyStateView class

Full-viewport empty-state widget.

Displays an illustration, a required title, an optional subtitle, and an optional call-to-action FilledButton.

The layout is a vertically and horizontally centred Column. If illustration is non-null it is shown with a maximum height of 180 px and a BankTokens.space6 gap below it. When illustration is null a themed fallback is drawn instead: a soft circle tinted with the theme primary colour holding a brand-tinted glyph, so empty moments never render as a bare wireframe.

BankEmptyStateView(
  illustration: Image.asset('assets/empty_transactions.png'),
  title: 'No transactions yet',
  subtitle: 'Your payments and transfers will appear here.',
  actionLabel: 'Make a Payment',
  onAction: () => navigator.push(PaymentRoute()),
)
