Description

Create a more advanced TypedDict or similar for annotating ASGI scope.

We could probably draw inspiration from the relevant parts of asgiref: https://github.com/django/asgiref/blob/main/asgiref/typing.py. Since these annotations are really trivial, we probably want just to reimplement the part that we use.

This would allow us to get rid of a bunch of typing ignores, see #2599.

Contributor guide

Research direction
Examine the asgiref typing module for ASGI scope and identify the relevant types used in Falcon. Then, implement a TypeDict or similar annotation for the scope dict, removing existing typing ignores.
