Add snapshot test: projectable constructor with NullConditionalRewriteSupport.Ignore

[Copilot]

No test coverage existed for [Projectable] constructors that use null-conditional operators (?.) together with NullConditionalRewriteSupport.Ignore. The syntax shown in the issue — a DTO constructor projecting from an entity with optional navigation properties — was untested.

Changes

• New snapshot testProjectableConstructor_WithNullConditionalIgnore in ConstructorTests.cs covering a constructor body that combines:
  • Null-conditional property access (source.Dossier?.Numero)
  • Null-conditional method call (source.Type?.ToString())
  • Ternary assignment (source.IsForfait ? "Yes" : "No")
  • Plain property mapping

[Projectable(NullConditionalRewriteSupport=NullConditionalRewriteSupport.Ignore)]publicProjection(Sourcesource){Libelle=source.Libelle;NumeroDossier=source.Dossier?.Numero;TotalHt=source.TotalHt;TypeValue=source.Type?.ToString();IsForfaitDisplay=source.IsForfait?"Yes":"No";}

The generator correctly strips ?. to plain . access under Ignore mode, producing a valid EF Core-translatable member-init expression. The snapshot locks in this behaviour as a regression guard.
