bug(MatDatePicker): NativeDatePicker not using the correct format initially

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

When I use the following setup:

```

provideNativeDateAdapter({
parse: {
dateInput: 'DD.MM.YYYY',
},
display: {
dateInput: 'DD.MM.YYYY',
monthYearLabel: 'MMM YYYY',
dateA11yLabel: 'LL',
monthYearA11yLabel: 'MMMM YYYY',
},
}),
{
provide: LOCALE_ID,
useValue: 'de-CH'
},
```

the DatePicker will show the date in the wrong format: "13.5.2025" instead of "13.05.2025". Why are the format options ignored?

Commencez avec NativeDatePicker et la configuration de provideNativeDateAdapter présentée dans l’issue, en utilisant la locale de-CH et le format dateInput fourni. Reproduisez l’affichage initial et recherchez pourquoi le format configuré est ignoré ; le travail est terminé lorsque le picker affiche initialement la date sous la forme "13.05.2025".
