fix(feeds): clip + preload content warning on cropped grid cells

- Pass contentScale through to ContentWarningOverBlurhash so grid cells
  (ContentScale.Crop) use fillMaxSize instead of forcing the image's
  native aspect ratio, keeping the blurhash and overlay within the cell.
- Clip the overlay to its bounds to stop the icon/button from drawing
  over neighboring cells or other components.
- Preload the image through Coil while the warning is visible so the
  image is cached by the time the user taps "Show anyway".
