Fix IPv6 address formatting in historical mode and increase API limit

- Add formatAddress helper to properly format IPv6 addresses as [ipv6]:port
  instead of ipv6:port which broke the extractIP parser
- Increase stored flow logs API limit from 10000 to 50000 to prevent
  cutting off records in larger time ranges
