[gitar-bot-staging]

Migrate Python Runtime from 3.9 to 3.10

Description

This PR migrates the entire codebase from Python 3.9 to Python 3.10 across all services and packages. The migration includes updating:

• CI/CD pipelines: GitHub Actions workflows for release, staging, and testing
• Service configurations: All Dockerfiles and setup.py files across 91 files
• Package dependencies: Updated Python version requirements in setup.py and setup.cfg
• Code compatibility: Minor adjustments to maintain compatibility with Python 3.10

Motivation

Python 3.9 reached end-of-life for security updates in October 2025. Migrating to Python 3.10 ensures:

• Security: Access to latest security patches and updates
• Performance: Benefits from Python 3.10 optimizations and improvements
• Features: Access to new language features like structural pattern matching, better error messages, and improved type hints
• Ecosystem compatibility: Better support for modern Python packages and dependencies

Key Changes

• Updated GitHub Actions workflows from python: ["3.9"] to python: ["3.10"]
• Modified all service Dockerfiles to use Python 3.10 base images
• Updated python_requires in setup.py files from ~=3.9 to ~=3.10
• Added deprecation warning filters in pytest configuration
• Updated constraints and dependency specifications

Impact

• 91 files changed across services, packages, and CI configuration
• No breaking changes to API or functionality
• Enhanced security posture through updated Python runtime
• Future-proofing for continued Python ecosystem support

References

• Python 3.10 Release Notes
• Python 3.10 Official Release

Test Plan

• CI/CD pipelines updated and functional
• All services build successfully with Python 3.10
• Dependency resolution works correctly
• No breaking changes introduced
