fix(auth): rename dict variable to avoid shadowing built-in

[hobostay]

Summary

• Rename the local variable dict to decoded_token in decode_jwt() to avoid shadowing the Python built-in dict type.

Why

In backend/chainlit/auth/jwt.py:35, the decode_jwt function assigns the decoded JWT payload to a variable named dict, which shadows Python's built-in dict type. While this doesn't currently cause a runtime error, it is a code clarity issue and could lead to subtle bugs if the built-in dict were needed later in the function (e.g., for type checking or casting).

Test plan

• Verify the existing JWT tests pass (uv run pytest tests/ -k jwt from backend/)
• Verify login/auth flows still work correctly

Summary by cubic

Renamed the local variable dict to decoded_token in decode_jwt() to avoid shadowing the Python built-in and improve code clarity. No behavior change; JWT payload handling remains the same.
