Bug

Zabbix alerts often arrive without a host name attached, in both the polling and webhook-push paths of the Zabbix provider.

• Polling (_get_alerts in keep/providers/zabbix_provider/zabbix_provider.py): the problem.get API call never requests host data (no selectHosts param), so pulled alerts have no host information at all.
• Webhook push (_format_alert): the installed Zabbix script sends the host as host_name / host_ip (matching the parameter names configured in setup_webhook), but the code reads hostName / hostIp instead — these keys never exist in the payload. The primary source, service ({HOST.HOST}), can be empty for problems tied to multiple hosts, and the fallback then silently returns None due to this key mismatch.
