Update script timestamp handling and dev promotion

Compute today's date once and use a consolidated patchBody for PATCH requests (including last_update_commit from PR_URL/COMMIT_URL). Add logic to promote dev scripts on merge: if record.is_dev === true, set is_dev to false and script_created to today, and log the promotion. Replace the previous duplicated date construction with the new patchBody.
