[Feature] Aggiunto supporto completo OLE DB per connessione database

Browse Source 
## Nuovi file
- DataConnection/DB/OleDbDatabaseManager.cs: Manager completo per connessioni OLE DB
  con supporto Task.Run() per operazioni sincrone, parametri posizionali '?',
  guard per piattaforma Windows, nessun supporto ChangeDatabaseAsync (no-op)
- DataConnection/DB/EF/SchemaProviders/OleDbSchemaProvider.cs: Schema provider per
  OLE DB, usa OleDbSchemaGuid per tabelle/colonne/chiavi primarie, mapping tipi dati
- CredentialManager/Services/OleDbProviderDiscoveryService.cs: Servizio di discovery
  provider OLE DB installati tramite registro Windows (HKEY_CLASSES_ROOT). Rileva
  9 provider noti: VFPOLEDB.1, Microsoft.ACE.OLEDB.12.0, Jet 4.0, SQLOLEDB, ecc.
  Mostra warning per provider solo 32-bit (VFPOLEDB, Jet)
- PUBLISH_32BIT_64BIT.md: Documentazione completa comandi pubblicazione per
  win-x64, win-x86 (richiesto per VFP), linux-x64, osx-x64, osx-arm64.
  Include prerequisiti VFPOLEDB, esempi connection string VFP, note Docker

## File modificati
- DataConnection/DB/Enums/DatabaseType.cs: Aggiunto valore OleDb dopo Odbc
- DataConnection/DataConnection.csproj: Aggiunto pacchetto System.Data.OleDb 9.0.3
- DataConnection/DB/OdbcDatabaseManager.cs: Fix bug ChangeDatabaseAsync con try-catch
- CredentialManager/Models/CredentialModels.cs: Aggiunto OleDb all'enum DatabaseType,
  BuildOleDbConnectionString() con supporto provider da AdditionalParameters,
  default VFPOLEDB.1, costruzione connection string con parametri VFP
- DataConnection/CredentialManagement/Models/CredentialExtensions.cs: Mappatura
  OleDb in ToDataConnectionDatabaseType() e ToCredentialDatabaseType()
- DataConnection/CredentialManagement/Services/DataConnectionCredentialService.cs:
  Aggiunto case OleDb in TestDatabaseConnectionAsync e metodo TestOleDbConnection()
  con apertura connessione via Task.Run() e gestione OleDbException dettagliata
- Data_Coupler/Services/DataConnectionFactory.cs: Aggiunto case OleDb per creazione
  OleDbDatabaseManager
- Data_Coupler/Program.cs: Registrazione IOleDbProviderDiscoveryService come Scoped
- Data_Coupler/Pages/CredentialManagement.razor: Aggiunta UI completa OLE DB con
  sezione dedicata Visual FoxPro (percorso .dbc/.dbf, Collating Sequence, DELETED),
  provider discovery con refresh, anteprima connection string, variabili di stato
  e metodi nel codice Blazor, sincronizzazione AdditionalParameters al salvataggio

## Compatibilità
- VFP 8.0/9.0: testato con VFPOLEDB.1, connessione file-based .dbc e .dbf
- Richiede pubblicazione win-x86 per driver OLE DB 32-bit
- AnyCPU non supportato per VFP (COM 32-bit)
