Fix dashboard-only permission leaking global extract access

[AtlasLabs797]

Motivation

• A global permission row with PuedeVerDashboard=true was being treated as full data access in ExtractosController, allowing non-admin users with dashboard-only permissions to read extractos across all cuentas and creating a cross-account data exposure that conflicts with UserAccessService semantics.

Description

• Removed p.PuedeVerDashboard from the global-access condition in GetAllowedAccountIds and the identical check in CanViewTitular within Atlas Balance/backend/src/GestionCaja.API/Controllers/ExtractosController.cs so global access now requires one of PuedeAgregarLineas, PuedeEditarLineas, PuedeEliminarLineas or PuedeImportar.
• Updated Documentacion/DOCUMENTACION_CAMBIOS.md and Documentacion/LOG_ERRORES_INCIDENCIAS.md to record the fix and associated it with version V-01.02.
• Preserved existing admin behavior and explicit per-CuentaId/TitularId permission handling.

Testing

• Performed static verification and diffs using sed -n, git diff and file inspection to confirm the condition was updated and documentation entries were added, and committed the change.
• Could not run dotnet build or dotnet test in this environment because dotnet is not available (command not found), so running dotnet test "Atlas Balance/backend/GestionCaja.sln" -c Release in an environment with the .NET SDK is pending.
