Rename docker-launchql.yaml to docker-constructive.yaml

[pyramation]

Summary

Renames .github/workflows/docker-launchql.yaml → .github/workflows/docker-constructive.yaml to align the filename with the current branding. No content changes — the workflow already uses "Constructive" internally (workflow name, image name, job names).

Verified that no references to docker-launchql exist across constructive, constructive-hub, constructive-db, or dashboard repos.

Review & Testing Checklist for Human

• Confirm no external systems (badge URLs, scheduled triggers from other repos, etc.) reference the old docker-launchql.yaml filename
