Fix error `get_class(): Argument #1 ($object) must be of type object,
null given`

this happens when added a new attribute to a resource.
the fix
7b19a0e
is to mutate the state during field dehydration to return new field type
instance when state is null
`formatStateUsing` doesnt set the instance during field hydration as it
only apply when the state is not null

other commits are some inconsistency that I found while troubleshooting,
it should still works without those commits

## Summary by CodeRabbit

* **Bug Fixes**
* Corrected breadcrumb navigation in the Product Variant admin area.
When managing variant identifiers, the final breadcrumb now links to the
Identifiers page instead of Inventory, aligning with the page context.
This improves navigation accuracy and consistency across the admin
interface, reducing confusion for users. No changes to data or
functionality—only the breadcrumb destination was updated wherever this
breadcrumb appears.
