Subject: [PATCH] test(core): remove redundant change detection configuration

OnPush is now the default change detection strategy, so the explicit test configuration is no longer needed.

Updates outdated Bazel test targets to use the zoneless configuration.

(cherry picked from commit 49a797f510cdaed40db31d32e1d7ca08df51396c)
