feat: Version 1.11.0 - Mejoras en auditoría, SLA, frontend y correcciones de sincronización

- Refactorización de endpoints de auditoría y helpers
- Mejoras en esquemas de auditoría (audit.py)
- Correcciones en endpoint SLA
- Actualizaciones en múltiples rutas del frontend interno:
  layout, tickets, usuarios, tenants, categorías, sistemas,
  SLA (at-risk, violations), auditoría (main + security), login, perfil
- Actualización de tailwind.config.js
- Eliminación de docs de versiones anteriores (CAMBIOS_v1.10.0, v1.8.0, OPTIMIZACIONES)
- Nuevos scripts de prueba: generate_security_test_data.py, generate_sla_test_data.py
- Script de prueba de sincronización crítica (test_critical_sync.ps1)
- README actualizado en scripts/

backend/app/api/v1/endpoints/sla.py
