Bug: NewsTickerView ticker loop resets prematurely due to unmeasured width

The ticker animation continuously checks if offset < -contentWidth to loop, but contentWidth starts at 0 and is only set asynchronously in the onAppear callback. This causes the reset condition offset < 0 to trigger immediately when animation begins, causing the offset to continuously jump back to 0 instead of smoothly animating until the content width is properly measured.
