fix(inventory): enforce consistent date format in document forms and views

- Add explicit date input format '%Y-%m-%d' to WriteOffDocumentForm and IncomingDocumentForm
- Disable localization for date fields to ensure yyyy-MM-dd format is used
- Set initial date value to current date in WriteOffDocumentCreateView's get_initial method
- Restrict warehouse queryset to active warehouses in forms initialization
- Improve date widget consistency by adding format parameter to DateInput widgets
