Install the Dell XPS 13 Panther Lake speaker firmware

Explicitly select the Omarchy Cirrus firmware when the installed package predates the 1028:0e54 aliases. Apply it during hardware setup and through an update migration, and request a reboot for each user until the firmware can load. Require the same minimum version in the offline package list so newer Arch snapshots keep their genuine firmware.
