API tests fail after release of Werkzeug v3.0.0

[asjohnston-asf]

Our API requirements specify serverless-wsgi=3.0.2. serverless-wsgi has a dependency issue with wekzeug=3.0.0 (released 2023-09-30):

logandk/serverless-wsgi#247

This causes imports to fail for our API app when running tests. I'd expect to see similar errors were we to release to production.

E   ImportError: cannot import name 'url_encode' from 'werkzeug.urls' (/opt/hostedtoolcache/Python/3.9.18/x64/lib/python3.9/site-packages/werkzeug/urls.py)

A short-term workaround is likely to specify Werkzeug==2.3.7 in requirements-apps-api.txt.

Unfortunately the tests are now failing with new errors after bumping serverless-wsgi to 3.0.3, see #1872.

Looks like the position argument order changed for set_cookie, so I updated our tests to use keyword arguments for that method, and now all tests pass.

I opted to keep the Werkzeug pin, now at 3.0.0.
