fix: detect touch screens dynamically instead of hardcoding Wacom device name

The xinput loop now scans all input devices at startup, matches anything
with "touch" or "finger" in the name (excluding touchpads/trackpads), and
attempts to enable Wacom touch gestures on each match. Non-Wacom devices
silently ignore the set-prop call, so the loop is safe on any hardware.
