Fix fuzzing workflow to build guest artifacts before fuzzing (#1153)

When the CI jobs were refactored to use reusable workflows, the dep_fuzzing.yml was changed to download guest artifacts instead of building them directly. However, the standalone Fuzzing.yml scheduled workflow was not updated to call dep_build_guests.yml first, causing all weekly fuzzing runs to fail with 'Artifact not found for name: rust-guests-release'. This adds the missing build-guests job as a dependency of the fuzzing job, matching the pattern used in ValidatePullRequest.yml.
