feat(udev): replace shokz blacklist with hwdb keycode override
The previous /etc/udev/rules.d/80-shokz-blacklist.rules deauthorized the
entire usbhid interface for the Shokz OpenMeet dongle (3511:2EF2) to stop
the host from powering off when the headset is turned off. That also
killed mic-mute, volume, and media keys on the same HID Consumer Control
node.
Replace it with a narrow hwdb override that remaps just the offending
scancode (Consumer page Power, c0030 -> KEY_POWER) to reserved on that
specific vendor/product. KEY_MUTE / volume / media keys keep working.
Add 'systemd-hwdb update' + an input-subsystem udevadm trigger to the
etc deploy hook so new hwdb files take effect immediately.
