Image Warp Tool arc options now close correctly

Arc Upper and Arc Lower have been improved so full-circle warps can connect cleanly without leaving a cut-off gap.

We fixed an issue in the Image Warp Tool where the Arc Upper and Arc Lower options could leave a missing cut-out section when the strength was pushed close to a full circle.

The arc strength can now reach 360, allowing circular wraps to close more cleanly. This makes the tool more useful for designs that need to follow a complete ring, circular stencil layout, or curved tattoo placement preview.

The fix applies to both the on-screen canvas preview and the downloaded image.
