Issue #3612201: Suppress the entity-storage phpstan rules on 2.0.x (removal lands in 4.0.0)
Proactive maintenance backport of the phpstan suppression from !403 (merged) / !402 (merged).
This branch is currently green, but its last pipeline predates the new phpstan-drupal EntityHandlerDirectInjectionRule family; a re-run would fail the same way 3.x did. Suppressing the two rules keeps it green without the BC-breaking refactor (which lands in 4.0.0, !402 (merged)).
No @deprecated docblocks: the storage properties are still used internally here, so deprecating them would make phpstan flag the internal access.
