fix: preserve long test and scanning name compatibility for 4.3.0

[huanghongbo-hhb]

Summary

• Backport the long test and scanning name compatibility fix to release-4.3.0.
• Preserve compatibility for existing long test and scanning names by normalizing generated workflow job names to lowercase and truncating them to 32 characters.

Why

• Some historical test and scanning configurations already use names longer than 32 characters.
• release-4.3.0 needs the same compatibility fix so existing data can still be saved and executed.

Main Changes

• Add a shared workflow job name normalization helper for test and scanning modules.
• Normalize generated job names to lowercase and trim them to the workflow job-name limit before validation.
• Keep test and scanning behavior consistent for create, update, and execution paths.

Risk / Compatibility

• Low risk: the change is scoped to generated workflow job names for test and scanning modules.
• This is a compatibility fix for historical long names; stored module names are unchanged.

Test

• GOCACHE=/private/tmp/zadig-go-build-cache go test -vet=off ./pkg/microservice/aslan/core/common/util
• GOCACHE=/private/tmp/zadig-go-build-cache go test -vet=off ./pkg/microservice/aslan/core/workflow/testing/service
