Fix CI test failures: regex pattern, mock patches, method signature

- Update regex pattern to handle Docker registry URLs with port numbers
- Fix mock patches to target correct import path (crewai_tools.CodeInterpreterTool)
- Fix integration test method signature for Crew._prepare_tools()
- All Docker image formats now validate correctly including my-registry.com:5000/python:latest
