AI summary

This pull request updates the project's dependency management and CI workflow to improve security auditing and dependency handling. The main changes include configuring Dependabot to monitor additional directories, updating CI requirements, and enhancing the pip-audit step in the workflow.

Dependency management improvements:

• Updated .github/dependabot.yml to monitor both the root directory and .github/utils for Python dependencies, ensuring that all relevant requirements files are kept up to date.

CI workflow enhancements:

• Modified the ci_tests.yml workflow to install dependencies from .github/utils/requirements_ci.txt instead of using editable installs, and added a step to generate a complete requirements file for pip-audit using pip-compile.
• Updated the pip-audit step to use the generated requirements file as input, improving the accuracy and coverage of dependency vulnerability checks.
