Fix mypy type errors in CLI migration to typer

- Fixed SafeBaseModel model_validate signature and return type
- Added null checks for optional attributes in codemods.py and session.py
- Fixed typer.Exit calls to use integer exit codes instead of strings
- Added missing file_content attribute to CodegenFunctionVisitor
- Implemented missing identify() method in RestAPI class
- Fixed Path return type issues by converting to string
- Added proper imports for rich and typing modules

Reduced mypy errors from 28 to 2 (only missing type stubs for requests)
