Clean up stale comments, dead test code, and flaky npm assertions

- Remove commented-out tests (route overlap, form data, file uploads)
- Remove stale TODO/FIXME comments from routes.py and api.py
- Make CLI npm error assertions case-insensitive and more flexible
  to handle different npm versions across CI environments
