[Feature/Perf] Ottimizzazioni bulk pre-discovery, batch deletion sync e supporto OLE DB / Salesforce client_credentials

## Bulk Pre-Discovery e riduzione query SQLite/SOQL

### KeyAssociationService — FindAssociationsByKeyValuesBulkAsync (nuovo)
- Aggiunta query bulk 'WHERE KeyValue IN (...)' per recuperare N associazioni con 1 sola query SQLite
  (chunking a 500 chiavi per rispettare il limite ~999 parametri di SQLite)
- Aggiunta interfaccia IKeyAssociationService e delegata in DataConnectionCredentialService / IDataConnectionCredentialService

### AssociationService — BatchFindOrCreateAssociationsAsync (nuovo)
- Nuovo metodo bulk che sostituisce i loop per-record durante l'analisi composite:
  1) 1 query SQLite bulk per tutte le chiavi
  2) Per le chiavi non trovate: SOQL 'IN (...)' su Salesforce in chunk da 200 via BatchExecuteQueriesAsync
     (ceil(K/25) HTTP Composite call invece di K singole)
  3) Salvataggio parallelo delle associazioni pre-discovery scoperte
- Fallback per-record automatico per client REST non Salesforce
- Aggiornata interfaccia IAssociationService con documentazione XML completa

### DataCoupler.razor.cs — STEP A/B nel flusso COMPOSITE
- Pre-Discovery spostata FUORI dal loop parallelo (STEP A, prima dell'analisi)
- associationsByKey pre-popolato con BatchFindOrCreateAssociationsAsync
- STEP B: il loop parallelo usa TryGetValue O(1) invece di query async per record
- Rimozione blocco ~40 righe di per-record lookup / fallback duplicati

## Salesforce Composite API — Batch Delete e Patch

### SalesforceServiceClient — metodi batch (nuovi)
- BatchDeleteEntitiesAsync: elimina N record con ceil(N/25) Composite call invece di N
- BatchPatchSingleFieldAsync: aggiorna un singolo campo su N record tramite BatchUpdateEntitiesAsync

### DeletionSyncService — refactoring batch
- ExecuteBatchedSalesforceDeletionsAsync: orchestrazione batch per Delete / Deactivate / Mark su Salesforce
- ExecuteSequentialDeletionsAsync: loop sequenziale esistente estratto in metodo riutilizzabile
- Dispatcher: Salesforce -> batch Composite, altri client REST -> sequenziale

## Supporto OLE DB (database)

### DatabaseSchemaProviderFactory
- Aggiunto case DatabaseType.OleDb -> new OleDbSchemaProvider() nel factory switch

### DatabaseMethod.cs
- Aggiunto metodo IsOleDbConnection() (parallelo a IsOdbcConnection())
- Query validation e manager temporaneo estesi a OLE DB oltre che ODBC
- GetLimitedQuery: aggiunto case OleDb -> 'SELECT TOP N FROM (subquery)'

## Salesforce OAuth2 — fix client_credentials

### CredentialService.cs
- Aggiunto 'GrantType' alla HashSet serviceSpecificKeys per preservarlo nella serializzazione AdditionalParameters

### DataConnectionCredentialService.cs
- Refactored BuildRestServiceOptions in helper statico riutilizzato da entrambi i metodi GetRestServiceOptions
- Mapping coerente ClientId/ClientSecret/GrantType per Salesforce (allineato a DataConnectionFactory)
- TestSalesforceOAuthLogin: branch esplicito per client_credentials (no username/password/token)
  con validazione preventiva ClientId+ClientSecret obbligatori
- Log flow label (password|client_credentials) in tutti i messaggi di autenticazione

## VS Code tasks

### .vscode/tasks.json
- Rimosso task generico 'Publish Data_Coupler'
- Aggiunti due task separati: win-x64 e win-x86, entrambi SingleFile + Self-Contained + ReadyToRun
