Add panel-to-PCB mounting system with M3 standoffs

Panel alignment: - PCB offset 10mm from panel top - Component holes aligned: OLED@25mm, jacks@45mm, button@58mm - 4x M3 standoff holes at corners (5,5), (35,5), (5,75), (35,75) Updates: - Panel SVG and spec aligned with PCB layout - Mounting holes added to PCB (Edge.Cuts layer) - Regenerated Gerbers with mounting holes - Updated autoroute.py to add mounting holes automatically DRC: 0 unconnected, 7 cosmetic errors (courtyard overlaps)
