feat(servicenow-iam): new ServiceNow IAM integration

Identity lifecycle on the sys_user table: get/create/update user (resolved by sys_id, username or email), enable user (active=true + locked_out cleared), disable user, and user field discovery via sys_dictionary for mapping. Basic or OAuth 2.0 (password grant) authentication, stdlib-only scripts. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
