Redundant client version check in AppHub

[ysmoradi]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

AppHub still checks if the client's version is supported, but this check is now handled in middleware before SignalR, making the AppHub check unnecessary.

Expected Behavior

Client version validation should only occur in one place (middleware).

Steps To Reproduce

Review version validation logic in both AppHub and ForceUpdate middleware.

Exceptions (if any)

No response

.NET Version
