test(permission): cover default active operation bitmap

[gummy789j]

Summary

Follow-up to #935.

• Extract the default active-permission operations bitmap into a named constant.
• Use clearer labels for operations that are present in the bitmap but not listed in the wallet-cli friendly label map.
• Add regression coverage to ensure the default active bitmap does not include ContractType 51 again.

Notes

The wording now distinguishes enum-backed unlisted operations from truly unknown operation codes:

• Unlisted op 51 (ShieldedTransferContract)
• Unknown op 255

Verification

• git diff --check
• Attempted ./gradlew test --tests org.tron.core.manager.UpdateAccountPermissionInteractiveTest, but this local machine does not have a Java Runtime installed.
