[DISC-008] Fix discovery feed infinite render loop

[chev0004]

Outline

Summary

Fixes a "Maximum update depth exceeded" crash on the discovery feed. The loading fallback renders DiscoveryPage without a profiles prop, so the profiles = [] default created a new array reference on every render and the prop-to-state sync effect (setProfileItems(profiles)) looped infinitely.
