Update: [AEA-5873] - direct lambda invocation refactor of the slackbot

[bencegadanyi1-nhs]

Summary

✨ New Feature

Details

added direct invocation to the slac bot lambda function to support upcoming regression testing

comes with the following work:

• direct invocation handler
• moves shared logic - created ai_processor.py service to avoid code duplicating
• types - there's already a good amount of typing in the codebase for this lambda function, but started extracting them to a more centralised location for reusability
• tests
