ImportError and incorrect Depends usage for `Request` in helper/auth.py

[Raihan2511]

There is an import error and incorrect use of FastAPI's Depends in superagi/helper/auth.py.

Request is used without importing it from fastapi.

Request is incorrectly wrapped in Depends(), which raises an AssertionError on startup.

This prevents the backend from starting in Docker.

Suggested fix:

• Add from fastapi import Request to the imports.
• Change the function signature to use request: Request without Depends().
