Graham McIntire f0fe3c025c fix: recover correct bandwidth rate when 32-bit SNMP counters wrap (#161)
Standard ifInOctets/ifOutOctets are 32-bit counters that wrap around
4,294,967,296 bytes (~4.3 GB). At 1 Gbps this wraps every ~34 seconds,
causing brief drops to 0 bps in traffic charts and capacity reports.

When prev > 2^31 and delta is negative, add 2^32 to recover the correct
rate. If the result is still negative (HC 64-bit counter after reboot),
clamp to 0. Small-value decreases (prev < 2^31) continue to clamp to 0
since they cannot be real 32-bit wraps.

Fixes both capacity.ex (utilization reports) and device_live/show.ex
(per-device traffic chart).
