feat: Implementar suite completa de tests de integración v1.9.0

- Agregar 46 tests de integración (auth, multi-tenancy, tickets)
- Crear estructura organizada tests/integration/ y tests/unit/
- Implementar fixtures completas para testing con BD separada
- Agregar conftest_integration.py con setup async
- Mover scripts PowerShell de testing a tests/scripts/
- Actualizar pytest.ini con markers y configuración
- Crear run_tests.sh script ejecutable para testing
- Documentación completa en README_TESTS.md
- Fix: Remover opciones obsoletas de TypeScript (importsNotUsedAsValues)

Tests implementados:
- Authentication: 15 tests (login, refresh, permisos, seguridad)
- Multi-tenancy: 13 tests (aislamiento, validaciones, seguridad B2B)
- Tickets: 18 tests (CRUD, filtros, permisos por rol)
- Unit: 10 tests básicos
- Verificación: 8 tests de setup

Base de datos de testing: servicemanager_test (separada de producción)
Cobertura estimada: ~40% (desde 5%)

Próximos pasos: Agregar tests de SLA, attachments, auditoría

+
+## 🚀 Ejecutar Tests
+
+### Prerequisitos
+
+1. **Servicios Docker corriendo:**
+   ```bash
+   docker-compose up -d postgres redis
+   ```
+
+2. **Base de datos de testing:**
+   ```bash
+   # Se crea automáticamente, pero si necesitas crearla manualmente:
+   docker-compose exec postgres psql -U servicemanager -c "CREATE DATABASE servicemanager_test;"
+   ```
+
+### Ejecución Rápida
+
+```bash
+# Dar permisos de ejecución al script
+chmod +x backend/run_tests.sh
+
+# Ejecutar todos los tests
+cd backend
+./run_tests.sh all
+
+# Ejecutar solo tests de autenticación
+./run_tests.sh auth
+
+# Ejecutar solo tests de multi-tenancy
+./run_tests.sh multitenant
+
+# Ejecutar solo tests de tickets
+./run_tests.sh tickets
+
+# Ejecutar con reporte de cobertura
+./run_tests.sh coverage
+```
+
+### Ejecución Manual con pytest
+
+```bash
+cd backend
+
+# Todos los tests de integración
+pytest -v -m integration tests/
+
+# Tests específicos por archivo
+pytest -v tests/test_auth_integration.py
+pytest -v tests/test_multitenant_integration.py
+pytest -v tests/test_tickets_integration.py
+
+# Con cobertura
+pytest --cov=app --cov-report=html tests/test_*_integration.py
+
+# Tests específicos por clase
+pytest -v tests/test_auth_integration.py::TestAuthentication
+
+# Test individual
+pytest -v tests/test_auth_integration.py::TestAuthentication::test_login_success
+```
+
+## 🧪 Cobertura de Tests
+
+### Tests de Autenticación (`test_auth_integration.py`)
+- ✅ Login exitoso con credenciales válidas
+- ✅ Login fallido (contraseña incorrecta, tenant inválido, usuario inactivo)
+- ✅ Refresh tokens (generación y revocación)
+- ✅ Logout y invalidación de tokens
+- ✅ Autorización por roles (ADMIN, AGENT, CLIENT)
+- ✅ Protección de endpoints
+- ✅ Seguridad de passwords (hashing, no exposición)
+
+**Total: 15 tests**
+
+### Tests de Multi-Tenancy (`test_multitenant_integration.py`)
+- ✅ Aislamiento de datos entre tenants
+- ✅ Usuario no puede ver tickets de otro tenant
+- ✅ Usuario no puede acceder por ID directo a datos de otro tenant
+- ✅ Usuario no puede modificar datos de otro tenant
+- ✅ Validación de X-Tenant-ID header
+- ✅ Validación de UUIDs
+- ✅ Permisos administrativos de tenants
+- ✅ Prevención de suplantación de tenant
+
+**Total: 13 tests** (CRÍTICOS para seguridad B2B)
+
+### Tests de Tickets (`test_tickets_integration.py`)
+- ✅ Crear ticket con validaciones
+- ✅ Listar tickets (vacío y con datos)
+- ✅ Obtener ticket por ID
+- ✅ Actualizar ticket (status, prioridad, asignación)
+- ✅ Filtros (por status, prioridad)
+- ✅ Permisos por rol:
+  - Cliente solo ve sus tickets
+  - Agente ve todos los tickets del tenant
+  - Admin tiene acceso completo
+
+**Total: 18 tests**
+
+## 📊 Métricas Objetivo
+
+```
+Cobertura actual:  ~5%  ❌
+Cobertura con estos tests: ~40%  🟡
+Cobertura objetivo: >70%  ⭐
+
+Tests totales: 46 tests de integración
+Tiempo ejecución: ~15-30 segundos
+```
+
+## 🔧 Configuración
+
+### Variables de Entorno para Testing
+
+El archivo `conftest_integration.py` usa:
+```python
+TEST_DATABASE_URL = "postgresql+asyncpg://servicemanager:servicemanager123@localhost:5432/servicemanager_test"
+```
+
+Para personalizar:
+```bash
+export TEST_DATABASE_URL="postgresql+asyncpg://user:pass@host:port/db_test"
+```
+
+### Markers de pytest
+
+Usa markers para ejecutar subconjuntos:
+```bash
+# Solo tests de integración
+pytest -m integration
+
+# Solo tests que usan BD
+pytest -m db
+
+# Solo tests de auth
+pytest -m auth
+
+# Excluir tests lentos
+pytest -m "not slow"
+```
+
+## 🐛 Troubleshooting
+
+### Error: "Database not found"
+```bash
+docker-compose exec postgres psql -U servicemanager -c "CREATE DATABASE servicemanager_test;"
+```
+
+### Error: "Connection refused"
+```bash
+# Verificar que servicios estén corriendo
+docker-compose ps
+
+# Reiniciar servicios
+docker-compose restart postgres redis
+```
+
+### Tests lentos
+```bash
+# Ver tests más lentos
+pytest --durations=10
+
+# Ejecutar en paralelo (requiere pytest-xdist)
+pip install pytest-xdist
+pytest -n auto
+```
+
+### Limpiar base de datos de testing
+```bash
+./run_tests.sh clean
+```
+
+## 📝 Agregar Nuevos Tests
+
+### Template para nuevo test
+
+```python
+import pytest
+from httpx import AsyncClient
+from sqlalchemy.ext.asyncio import AsyncSession
+
+pytest_plugins = ['tests.conftest_integration']
+
+@pytest.mark.integration
+@pytest.mark.db
+class TestNuevaFuncionalidad:
+    """Descripción de la funcionalidad."""
+    
+    async def test_caso_exitoso(
+        self,
+        client: AsyncClient,
+        test_tenant: Tenant,
+        auth_headers_admin: dict
+    ):
+        """Test del caso exitoso."""
+        response = await client.get(
+            "/v1/endpoint/",
+            headers={
+                **auth_headers_admin,
+                "X-Tenant-ID": str(test_tenant.id)
+            }
+        )
+        
+        assert response.status_code == 200
+        # Más assertions...
+```
+

+- [ ] Tests de comentarios en tickets
+- [ ] Tests de attachments (uploads)
+- [ ] Tests de auditoría
+- [ ] Tests de notificaciones email
