fix(profile): don't nest verticalScroll in the Account hub

ProfileContent owned a verticalScroll while the Account hub also wrapped it in a
scrolling Column, throwing IllegalStateException (infinite-height measure) at
render. ProfileContent is now a plain content block; the hub scrolls header+menu
together, and UserProfileScreen supplies its own scroll. Verified live on emulator.
