defineEntity

This composable is used in Page-component to determine the entity based on the previous entity. For example:

/customers/:customerId/contacts/:contactId

The previous injected entity was customers, so this entity is contacts.

If the $entity is not defined yet, it means that we are in the root. So, in the above example the first entity is customers.
