Shorten periodic rebind interval from 1-32h to 2-12h (avg ~7h)

GFW typically detects WireGuard traffic on a single port within 24
hours. The previous 1-32 hour interval (avg 16.5h) was too close to
this detection window. The new 2-12 hour range (avg ~7h) stays well
below the detection threshold while keeping SSH coordination overhead
minimal (~3.4 rebinds/day).
