feat: store and display per-patient sync detail in historial

- Add detalle_json column to sync_wa_log via migration
- guardar_sync_log() now stores doc, nombre, action, examenes count per patient
- Historial table shows "Ver N" button that expands a row with patient list,
  action badge (Nuevo/Actualizado/Omitido) and exam count per patient
