KatFullScreenImageScreen class
Full-screen, pinch-to-zoom viewer for a single image.
Wraps PhotoView in a bare Scaffold with a default AppBar, so when
pushed via Navigator.push the implied back button is enough to close
the viewer.
Use KatFullScreenImage.network for an image served over the network,
or KatFullScreenImage.asset for one bundled in the host app's own
asset bundle. Each named constructor pins down exactly one image source,
so - unlike a pair of nullable parameters - an instance can never end up
built with neither or both set.
A broken or unreachable image renders a placeholder icon instead of crashing the screen with an uncaught image-loading error.
