Pull request overview

This PR enhances the Robot Framework Docker test suite by improving test metadata (IDs/tags/docs) and cleaning up minor formatting in shared keywords, aiming to make test runs easier to filter and understand.

Changes:

• Added numeric IDs, standardized tags, and expanded per-test documentation in test/docker-tests.robot.
• Simplified/synchronized compose test file references and updated some teardown paths in compose scenarios.
• Fixed minor spacing/formatting in test/keywords.resource (loop indentation and header dictionary spacing).
