Describe the problems in the documentation

The instructions for setting up the Docker container to run the client example notebooks should be included in the notebook itself in addition to the README file. This is important because users might be directed to the notebook directly from the "Quickstart" guide without encountering the client_examples README. Consequently, they may encounter errors related to data paths and environment variables.

Opened PR #1633 to add notebook-local setup guidance and environment-variable overrides for the client example notebooks. This keeps the notebooks usable when reached directly from the quickstart docs and aligns the sample paths with the client container layout.
