feat: Add orm for Tools and clean up Tool logic

[mattzh72]

Description

This is a large refactor of how Tools are being instantiated today.

• We create a Tool ORM model and a corresponding Tool manager.
• We change the Tool interface to require both user_id and organization_id on creation
• We integrate these changes across all the surfaces in the codebase (there are many) that use Tools

@norton120 again credits for inspiring the orm model for tool

Testing

We write a suite of unit tests for the tool manager interface and also adapt existing tests to use our new interfaces.
