Fix encrypted password pull consumer commit mode

[Caideyipi]

Description

• Set the encrypted-password pull consumer regression test to manual commit mode.
• Keep it consistent with consume_data(), which explicitly commits polled messages.
• Avoid a race where the default auto-commit worker commits the same message before the test's manual commit, causing a partially accepted duplicate commit.

Verification

• mvn spotless:apply -pl integration-test -P with-integration-tests
• git diff --check -- integration-test/src/test/java/org/apache/iotdb/subscription/it/triple/treemodel/regression/param/IoTDBEncryptedPasswordPullConsumerIT.java
• mvn -Ddevelocity.off=true verify -DskipUTs -Dit.test=IoTDBEncryptedPasswordPullConsumerIT#testSubscribeWithEncryptedPassword -DfailIfNoTests=false -Dfailsafe.failIfNoSpecifiedTests=false -pl integration-test -P with-integration-tests,MultiClusterIT2SubscriptionTreeRegressionMisc (target test was discovered, but skipped locally because the test cluster failed to start: SeedConfigNode not alive / Empty configNode set)
