wireguard-tools: increase watchdog idle timeout to 180s

Browse Source 
The current 150s watchdog timeout is too aggressive, leading to
premature hostname re-resolution on alive connections.

Even with a 25s keepalive, handshakes may not occur within the 150s window.
Increasing the timeout to 180s aligns the watchdog with WireGuard's
REJECT_AFTER_TIME constant, ensuring we only re-resolve when the connection
is truly considered dead.
