Subject: [PATCH] Fix SessionHttpContext to delegate attributes via __getattr__

The previous implementation eagerly copied ASGI-specific attributes
(pathsend, receive, send) from the wrapped context, which crashed under
RSGI because RsgiContext does not have those attributes. Now
SessionHttpContext delegates all non-overridden attributes to the wrapped
context via __getattr__, making it protocol-agnostic.
