Handle several minor issues on the Copilot Studio module

[AvishaiEZen]

Handle several minor issues on the Copilot Studio module:

• Add gitignore to several more directories (internal_result, final_results)
• rename enum module to avoid naming conflicts in the future
• Add missing annotations in code for clarity
• Tenant default environment found? -> change this text to be more accurate in report
• Add 'To continue, please login' as a possible authentication msg (currently this is a FP)
• Identify MSFT API 401 msg for Entra ID auth recent change (not an FP but currently showing a timeout in the terminal since not explicitly identified). Possibly use the opportunity to elaborate on the estimated auth according to the error (will reduce timeout msgs and provide more insights in the report)
