Graham McIntire	86db804729	fix: correct 32-bit SNMP counter wrap detection for all traffic calculations (#163) ... The wrap detection only applied the 2^32 correction when the previous counter was in the upper half of the 32-bit range (> 2^31). On fast links, counters wrap regardless of where in the range they sit. Three graph rendering paths had no wrap detection at all, just max(0). Consolidated all bps calculations into a single public Capacity.calculate_bps/3 that always tries the 2^32 correction for negative deltas. 64-bit HC counter resets remain clamped to zero since the corrected delta stays negative.
