feat: ottimizza interfaccia query personalizzate rimuovendo messaggi verbosi

Browse Source 
- Rimossi messaggi di successo per validazione query per ridurre ingombro visivo
- Eliminati alert informativi delle colonne rilevate dalla query
- Rimossa notificazione "Query validata!" nella sezione mapping
- Mantenuti solo i messaggi di errore quando necessario
- Migliorata UX con interfaccia più pulita e focalizzata sull'essenziale
- Funzionalità di estrazione colonne e mapping completamente preservata
