Remove python-jose from dependencies

@moto-timo mentioned that:
>Snyk is highlighting python-jose as having [High vulnerabilities](https://security.snyk.io/package/pip/python-jose). One of the suggested replacements is [PyJWT](https://pypi.org/project/PyJWT/).

We need to remove python-jose if possible.

Search the repository's dependency manifests and Python imports for python-jose, then inspect each usage to determine whether it can be removed or needs PyJWT. Confirm that python-jose is absent or replaced as appropriate, and run the relevant existing test suite to verify authentication behavior.
