Summary of Changes

Hello @parthea, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on essential maintenance and dependency management. It updates the core python-librarian-generator Docker image, streamlines authentication parameter passing in client library transports, and advances the MyPy configuration to target Python 3.14. It also explicitly lists cryptography as a direct dependency where needed. These changes collectively enhance the project's stability, security, and future compatibility.

Highlights

Librarian Image Update: The python-librarian-generator Docker image has been updated to a new SHA256 hash, ensuring the use of the latest version of the librarian tool.
Authentication Refactoring: Authentication credential handling in base transport files across numerous client libraries has been refactored. The scopes_kwargs dictionary is now removed, with its contents passed directly to google.auth.load_credentials_from_file and google.auth.default for improved clarity and direct argument passing.
MyPy Python Version Update: The target Python version for MyPy configurations in several packages has been updated from 3.7 to 3.14, reflecting an advancement in the project's Python version compatibility and type checking standards.
Dependency Management: The cryptography library has been explicitly added as a direct dependency of google-auth in various constraint files, solidifying dependency resolution and preventing potential issues.

Code Review

This pull request is an automated update from the librarian tool. It updates the generator image and applies resulting code changes across many packages. The changes primarily involve refactoring authentication scope handling, adding cryptography as an explicit dependency, and updating the python_version for mypy. My review found a significant issue with the mypy configuration: the python_version is set to 3.14, which is an invalid version and will likely break static analysis. I have added comments to all affected mypy.ini files with a suggested fix.
