Part A — MedioId → ProductTypeId rename across all C# layers:
Domain, Application, Infrastructure, API, all test projects.
Solution was non-compilable after BD refactor (5c1675e); now compiles clean (0 errors).
Part B — PATCH /api/v1/admin/chargeable-chars/{id}/reactivate:
ReactivateChargeableCharConfigCommand/Handler, SP guard maps 50410/50411/50412
→ ChargeableCharConfigReactivationNotAllowedException(Reason) → HTTP 409.
Part C — DELETE /api/v1/admin/chargeable-chars/{id}:
DeleteChargeableCharConfigCommand/Handler, physical DELETE on SYSTEM_VERSIONED table.
KeyNotFoundException → 404 via ExceptionFilter.
Tests: +30 unit tests (TDD RED→GREEN). All 1266 unit tests pass.
Fix all test compilation errors caused by T400.10/T400.20/T400.30:
- Handler constructors: add TimeProvider.System as last argument
- Domain mutator calls: add DateTime.UtcNow as explicit 'now' argument
- AuditLogger/SecurityEventLogger Build() helpers: add TimeProvider.System
- JwtService test constructors: add TimeProvider.System
Cat2 coverage already present in TimeProviderArgentinaExtensionsTests.cs:
FakeTimeProvider proves GetArgentinaToday() returns ART civil date, not UTC.
Eliminar SecuenciaComprobanteTests, ReservarNumeroCommandHandlerTests,
GetProximoNumeroQueryHandlerTests y 7 tests de integración en
PuntosDeVentaControllerTests (reserva/proximo/concurrencia/secuencialidad).
SqlTestFixture ahora limpia SecuenciaComprobante+SP si existen (drops idempotentes)
y solo crea PuntoDeVenta + temporal table.
