fix(scaffold-module): address review feedback from tiagoek

- Remove SAP-internal Artifactory URL from user-guide.md template;
  replace with plain `uv add sap-cloud-sdk`
- Remove incorrect token_url derivation from service URL; BTP binding
  schemas vary and the UAA URL must be read from the binding, not
  guessed from the service URL
- Expand Phase 5 self-review to run the full local gate: ruff check,
  ruff format --check, ty check, and pytest (not just ruff check)
