fix(logind): ignore KEY_POWER short-press to stop Shokz dongle shutdowns
The Shokz OpenMeet dongle (3511:2EF2) emits KEY_POWER on USB
enumeration and on headset power transitions, which logind handles
with HandlePowerKey=poweroff and immediately shuts the host down.
The previous attempt — an hwdb scancode remap of c0030 to reserved —
sets the udev property correctly but the kernel does not honor
EVIOCSKEYCODE for this device's HID consumer-page mapping (verified:
KEY_POWER 116 still appears in the evdev keymap after udevadm trigger
and libinput still reports it). Drop the hwdb file and the
systemd-hwdb hooks from the etc deploy script.
Replace with a logind drop-in that sets HandlePowerKey=ignore and
HandlePowerKeyLongPress=poweroff. Single-tap power events from any
source become no-ops; a 5s hold still shuts the machine down, so the
real hardware-power-button safety net is preserved. Add a HUP to
systemd-logind in the deploy script so the change takes effect
without restarting the daemon.
