Fix regex parsing of airmon-ng monitor interface name

The previous regex incorrectly captured "for" from airmon-ng output
like "monitor mode enabled for [phy0]wlp3s0 on wlp3s0mon". Now uses
a more specific pattern that looks for "on <interface>mon" first,
with fallback to any word ending in "mon".
