Map SLOT_NAME_DPI_BUTTON to DpiToggle and add verification tests - #703

Greptile Summary

This PR recognizes Logitech’s alternate DPI button slot name so the MX Vertical’s top button appears as the existing DPI toggle control.

• Maps both SLOT_NAME_MODESHIFT_BUTTON and SLOT_NAME_DPI_BUTTON to ButtonId::DpiToggle.
• Adds unit coverage for both slot-name variants.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Hi @AprilNEA, I really enjoy your app - and even more so now that I’ve found a workaround to get the Top Button working on my MX Vertical! I truly appreciate your hard work on this project. Since the Logitech MX Vertical is one of the most widely used ergonomic mice on the market, I wanted to gently bump this PR to see if it could get a bit more visibility. No rush at all, I just thought natively integrating this fix would be a huge quality-of-life improvement for many users

Thanks for the kind words and for confirming the workaround!
