- El filtro usaba hora local que se convertía incorrectamente a UTC
- Los registros de 'hoy' aparecían en 'ayer' por desfase horario
- Ahora trabaja directamente en UTC para consistencia
- Afecta todos los filtros: today, yesterday, last7days, last30days
- Custom dates también parseados correctamente como UTC
