<fix>[account]: transfer all resources to admin when deleting users

Background: Unlike ZStack Cloud which has strong multi-tenant isolation with
dedicated resource lifecycle per tenant, ZSphere adopts a different model where
resources should be preserved when an account is deleted. Instead of cascading
deletion to all owned resources, we want to maintain the resources and transfer
their ownership to the admin user.
This commit removes AccountVO.class.getSimpleName() from getEdgeNames() in
all CascadeExtension classes across both core and premium modules, preventing
the cascade deletion framework from triggering resource deletion when an
account is deleted.
After this change, deleting an account will no longer trigger cascade deletion
of associated resources. The resources will remain in the system and can be
adopted by the admin user through the existing adminAdoptAllOrphanedResource()
mechanism.

Resolves: ZSV-11415
