Samenvatting van de fixes:

1. min-w-0 en box-border toegevoegd aan inputClassName en selectClassName - dit voorkomt dat inputs buiten hun
  grid-cellen groeien
  2. overflow-hidden toegevoegd aan de DialogContent - voorkomt dat content buiten de modal zichtbaar is
  3. overflow-hidden toegevoegd aan het form element
  4. Grid layout verbeterd voor datum/tijd: grid-cols-[1fr_auto_auto] met vaste breedte (w-24) voor de tijd inputs,
  zodat de datum meer ruimte krijgt
  5. min-w-0 toegevoegd aan alle grid children voor Type/Locatie

  Deze wijzigingen zorgen ervoor dat:
  - Invoervelden nooit buiten hun containers groeien
  - De modal content netjes binnen de grenzen blijft
  - De datum input meer ruimte krijgt dan de tijd inputs
  - Select dropdowns niet overflow veroorzaken
