adminandClaude Opus 4.7 8342904488 fix(firmware/lib): wrap-safe millis() comparison in net_guard reconnect timer ...

net_guard_tick() compared absolute uint32_t millis() values:
  if (millis() < s_next_retry_ms) return;
This is broken across the ~49.7-day millis() wrap: depending on which
side of the wrap each value lands, retries either tight-loop or stall
indefinitely. The device is designed for multi-month uptime, so this
is a real production case, not a theoretical one.

Replace with the standard wrap-safe pattern using a signed difference.
