APP-6884 - Add-auto-promote-stages

[danielreJfrog]

Summary

• Add --auto-promote-stages to app-create and app-update so CLI can set ordered lifecycle stages on create/update.
• Empty --auto-promote-stages on update sends [] to turn auto-promotion off; omitting the flag leaves current stages unchanged.
• Cover flags, spec JSON, table output ordering, and e2e create/update/clear paths.

Test plan

• go test ./... and go vet ./...
• jf apptrust app-create my-app --project=default --auto-promote-stages="DEV;PROD"
• jf apptrust app-update my-app --auto-promote-stages="DEV;PROD" then --auto-promote-stages=""
• Create from --spec with auto_promote_stages
• Confirm --spec cannot be combined with --auto-promote-stages
