Graham McIntie de455d1cf4 fix: improve bandwidth counter handling to match LibreNMS approach (#168 )

- Clamp negative counter deltas to zero instead of attempting 32-bit wrap
  correction (matches LibreNMS behavior — wraps are indistinguishable from
  HC counter resets, so discard the ambiguous data point)
- Add rate sanity check: discard values exceeding 400 Gbps as counter anomalies
- Add 4-byte binary decoding for 32-bit SNMP counters in decode_snmp_value
- Track HC vs standard counter usage per interface stat (is_hc field)
- Add migration for is_hc column on snmp_interface_stats
- Update tests to match new clamping behavior
