fix(ui): crop width and height inputs limited to -1 of max (#15101)

### What

Crop width/height inputs can now be incremented to the original image
dimensions

### Why

Users were unable to increment crop dimensions back to the full original
size using arrow keys. The inputs would max out at `originalSize - 1`,
even though typing the max value directly worked fine.

### How

Removed redundant pixel-based validation in `fineTuneCrop` that was
blocking state updates when dimensions equaled the original size. The
percentage-based validation already handles invalid values (≤0% and
>100%).

Fixes #14758
