Media Editor: Consistent width for Scale and Crop inputs

[sabernhardt]

For version 5.3, the width for Scale Image and Image Crop inputs was increased from 50 to 80 pixels on larger screens (ticket #47115, commit 46359). However, I missed how the stylesheet resets that width to 60px for smaller screens (up to 782px viewport width).

The current 60 pixels may be enough for most people, but there is plenty of space available to make them consistent at 80px.

with a significant increase in text size, 4 digits are visible in 80px-wide inputs

patch removes width adjustment (instead of setting the same value again)
