[Bug]: Python happy path client still uses outdated import paths after v2026-01-23 update

[KingAlesh]

Describe the bug

Hello,
I was testing the Python happy path client in:

samples/rest/python/client/flower_shop/simple_happy_path_client.py

after the recent update:
"fix: Update python server /samples to UCP 01-23 version"

The server-side changes appear to have been updated to the new SDK naming, but the client still contains old import paths (e.g. *_req modules).

For example, I had to update imports like:

from ucp_sdk.models.schemas.shopping import checkout_create_req

to:

from ucp_sdk.models.schemas.shopping import checkout_create_request

(and similarly for item, line_item, payment, etc.)

After updating these imports, the client runs successfully.

Happy to open a PR to update the client imports if that’s helpful.

To Reproduce

1. Clone the samples repository

2. Ensure python-sdk v2026-01-23 is installed

3. Run the client:

   uv run simple_happy_path_client.py --server_url=http://localhost:8182

4. Observe import errors related to modules such as:

   • checkout_create_req
   • item_create_req
   • line_item_create_req

Expected behavior

The client should run successfully against python-sdk v2026-01-23 without requiring any manual changes to import paths.
