[fix](fe) Restrict frontend config updates to root in cloud mode

[gavinchou]

What problem does this PR solve?

Issue Number: None

Related PR: None

Problem Summary:

The Nereids migration of ADMIN SET FRONTEND CONFIG retained the global ADMIN privilege check but omitted the cloud-mode root-only restriction from the legacy DDL executor. This PR restores that restriction: in cloud mode, an ordinary admin is rejected and root remains allowed. Non-cloud behavior is unchanged.

Release note

Restrict ADMIN SET FRONTEND CONFIG to root in cloud mode.

Check List (For Author)

• Test

  • Regression test
  • Unit Test
    • AdminSetFrontendConfigCommandTest#testCloudAdminCannotSetFrontendConfig
    • FE build with build.sh --fe
  • Manual test (add detailed scripts or steps below)
  • No need to test or manual test. Explain why:
    • This is a refactor/code format and no logic has been changed.
    • Previous test can cover this change.
    • No code files have been changed.
    • Other reason

• Behavior changed:

  • No.
  • Yes. In cloud mode, non-root admin users can no longer update FE runtime configuration.

• Does this need documentation?

  • No.
  • Yes.
