Split docker tests fixtures

Title

Split docker test fixtures

---

Description

Splits docker test fixtures so that individual docker-compose projects can be setup and torn down independently.

This improves single test performance (e.g., when SQL tests don't need to setup SSH test fixtures) and parallelism by allowing each to operate independently.

Pull Request Overview

This PR refactors docker test fixtures to enable independent setup and teardown of different docker-compose projects. This improves test performance by allowing tests to only initialize their required services (e.g., SQL tests don't need SSH fixtures) and enhances parallelism by making docker-compose projects independent.

Key Changes

• Moved shared docker fixture logic from conftest.py to a new docker_fixtures_util.py module
• Added fixture-specific docker_compose_file and docker_compose_project_name fixtures in SQL and SSH test suites
• Updated multiple conftest.py files to import and expose the relocated docker fixtures
