Pull request overview

This pull request fixes the orientation of holes and pads in the StampBoard component by correcting the coordinate system calculations. The changes ensure that pads and holes are placed on the correct board edges according to standard coordinate conventions (positive x = right, negative x = left, positive y = top, negative y = bottom).

Changes:

• Swapped x-coordinate calculations for left and right leads to place them on the correct sides of the board
• Flipped y-coordinate calculations for top and bottom leads to position them properly relative to the board center
• Updated the example to demonstrate the corrected layout with a different lead count configuration

Please add test for this.

can you improve the camera, maybe add a second view preset like "top_angled" that presents a more "top" view (but not completely the top, just a slight angled)
