fix(db): use int for netspeed_active to prevent overflow

GetZoneStatsData and GetZoneStatsV2's netspeed_active values can
exceed 2 billion, causing 32-bit integer overflow. Changed from
int32/uint32 to int (64-bit on modern systems) to handle large
network speed totals.

- Update sqlc column overrides to use int type
- Fix type compatibility in dnsanswers.go zoneTotals map
- Regenerate database code with new types
