CLEmptyState class

Stato vuoto standard — Tier 1.

Icona (opzionale) + titolo + messaggio (opzionale) + azione (opzionale), centrati, con spaziatura e tipografia dai token. Sostituisce i tanti Center(child: Text('Nessun ...')) ad-hoc sparsi nelle pagine, dando un layout coerente e uno slot azione.

Esempi:

// Minimo — drop-in per "Nessun X":
CLEmptyState(title: 'Nessuna sede')

// Completo:
CLEmptyState(
  icon: Icons.inbox_outlined,
  title: 'Nessun accreditamento',
  message: 'Aggiungi il primo accreditamento per iniziare.',
  action: CLButton.primary(text: 'Aggiungi', onTap: _add, context: context),
)
