// Descrizione Dettagliata del File app.go
// Gestione degli Errori: Assicura che ogni passaggio dell’inizializzazione sia gestito correttamente e che eventuali errori nel caricamento dell’ultima versione della blockchain siano gestiti con un panic.
// Importazioni: Include tutti i pacchetti richiesti da Cosmos SDK e i moduli personalizzati specifici per la blockchain Experience (registration, exp, therapy).
// Costanti e Variabili Globali: Definisce le costanti globali come AppName e DefaultNodeHome e imposta ModuleBasics e ModuleAccountPermissions per la configurazione dei moduli.
// Struttura App: Definisce la struttura App che contiene tutti i keeper dei moduli standard di Cosmos SDK e quelli personalizzati. Include anche il Module Manager (mm) e il Simulation Manager (sm).
// Funzione NewApp: Inizializza l’applicazione, configura i keeper per ogni modulo e imposta il manager dei moduli. Configura il router per gestire le transazioni e aggiunge tutti i moduli necessari al Module Manager e al Simulation Manager.
// Gestione degli Errori: Assicura che ogni passaggio dell’inizializzazione sia gestito correttamente e che eventuali errori nel caricamento dell’ultima versione della blockchain siano gestiti con un panic.
