The B9406CAA ships with a Focal Tech FT9349 ESS sensor on USB 2808:a97a.
Mainline libfprint at 1.94.x lacks the open-source focaltech_moc driver
entirely; the driver is in libfprint master under LGPL but no upstream
release has shipped with PID 0xa97a in id_table[]. OPR carries
libfprint-git with both the driver and the PID patch.
Inline detection in omarchy-setup-fingerprint via /sys/bus/usb so we
don't introduce a one-off hardware-match script just for this case.
The check is cheap and runs only when the user opts into fingerprint
setup (lazy install pattern). Once upstream libfprint catches up, the
extra branch becomes harmless because libfprint-git provides=libfprint.
Tested end-to-end on B9406CAA: fprintd-enroll completes, fprintd-verify
matches enrolled fingers and rejects others, survives suspend/resume.

* 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.
