Issue #3612201: Suppress the entity-storage phpstan rules on 3.x (removal lands in 4.0.0)
Backport companion to !402 (merged) (which fixes the rules properly on 4.x).
3.x is a maintenance branch, so the BC-breaking storage refactor cannot land here (it removes protected storage-cache properties from public base classes). Instead this suppresses the two new phpstan-drupal rules so the branch pipeline stays green:
drupal.entityStoragePropertyAssignmentdrupal.entityStorageDirectInjection
The actual removal lands in 4.0.0 (see !402 (merged)). reportUnmatchedIgnoredErrors is already false, so the ignores are harmless if a rule does not fire.
@deprecated docblocks were intentionally not added: the storage properties are still used internally on this branch, so marking them deprecated would make phpstan's deprecation rule flag that internal access and generate new violations.
