refactor(jans-cedarling): better examples for python binding

[SafinWasi]

Description

Currently the example script in the python bindings folder is disorganized, with a lot of code thrown at the user with not a lot of explanation. This needs to be refactored into smaller script examples for unsigned and multi issuer authz with separate policy stores.

I looked into this and I’d like to work on it.

The main problem is that the current example.py mixes two unrelated flows, unsigned authorization and multi-issuer authorization, into one script with shared import-time setup and very little explanation. It also uses one generic policy store for both scenarios.

Proposed approach:

• split it into two standalone examples under examples/:
  • unsigned_authz.py
  • multi_issuer_authz.py
• add scenario-specific policy stores under example_files/
• keep only a small shared helper for bootstrap/path setup
• update the README with separate run instructions for each example
• remove the old monolithic example.py

If that sounds good, I can put up a PR for it.

Hi @pradhankukiran , are you familiar with cedarling interfaces and the python binding? If so I can assign you the PR.

[pradhankukiran]

Yes, I’ve been digging into the Python bindings and the Cedarling authz interfaces. I understand the authorize_unsigned and authorize_multi_issuer flows, the policy store structure, and how the bootstrap configuration wires everything together. Happy to take this on.
