On Apple Silicon, the battery shows up as macsmc-battery instead of BAT0.
All battery scripts assumed BAT* naming — which worked on x86 since upower
names the device battery_BAT0, but fails on Asahi where the kernel device is macsmc-battery.
The Ctrl+Alt+Super+B hotkey showed nothing and the low battery monitor never activated.

Fixed omarchy-battery-present to check all power supply entries — the existing type check
already filters out AC adapters. Fixed the four upower scripts to grep for /battery_ prefix
which upower uses for all batteries regardless of kernel device name. Fixed the migration
script to use omarchy-battery-present so the timer activates on fresh Asahi installs too.
