iOS data-loading fix

Build 52 fixes authenticated snapshot downloads so valid signed-in requests do not depend on a separate download token.

Signed-in data loading

The iOS data loader uses the signed-in session for snapshot downloads. A valid response no longer fails simply because a separate download token is absent.

What to check

When this fix is included in your installed build, check that Home, Games, and Markets load after sign-in and after returning from the background. Report the installed build, screen, sport, and steps if loading fails.

This fix is merged into the Build 52 code. TestFlight and App Store availability have not been confirmed.
