* Fix disable-while-typing on ASUS ROG Flow Z13 detachable keyboard
* Replace lsusb with DMI detection for Z13 keyboard
* Use omarchy-hw-match instead of custom z13_present function
* Add ASUS ExpertBook B9406 display and touchpad fixes for Panther Lake
* Drop B9406 migration
Per DHH's review: the migration's audience is essentially nobody.
Anyone running Omarchy on B9406 today is doing so via nomodeset
manually at every boot, not via a working unmodified install. Fresh
installs after this PR ships will pick up the fixes through the
hardware-match install hook; no migration needed.
