Disko auto-generates fileSystems with by-partlabel paths, but
for manual install via loop devices we need by-label paths.
mkForce ensures our paths win during evaluation.
- Add disko flake input + partition config (/boot/firmware, /, /home)
- Add cm5-backlight-fix service as display fallback
- Add enable-gpio23-usb-hub service for internal USB hub
- Add mt7921u kernel module for MediaTek AC1200 WiFi
