Update WAF service types and migration for listener configuration

- Modify `ListenerWaf` struct to use single `HostsAndPort` field instead of separate `Hosts` and `Port`
- Update `EnableListenerWafsReq` to use `ListenerWaf` slice for listeners
- Change `waf_services` table migration to use `BIGINT` and `AUTO_INCREMENT`
- Adjust `EnableListenerWafs` method to parse new listener format
- Add logging for listener name during WAF configuration
