🚦 feat(uptime-kuma): support custom category names & monitor subgroup rendering

Backend
• controller/uptime_kuma.go
  - Added Group field to Monitor struct to carry publicGroupList.name.
  - Extended status page parsing to capture group Name and inject it into each monitor.
  - Re-worked fetchGroupData loop: aggregate all sub-groups, drop unnecessary pre-allocation/breaks.

Frontend
• web/src/pages/Detail/index.js
  - renderMonitorList now buckets monitors by the new group field and renders a lightweight header per subgroup.
  - Fallback gracefully when group is empty to preserve previous single-list behaviour.

Other
• Expanded anonymous struct definition for statusData.PublicGroupList to include ID/Name, enabling JSON unmarshalling of group names.

Result
Custom CategoryName continues to work while each uptime group’s internal sub-groups are now clearly displayed in the UI, providing finer-grained visibility without impacting performance or existing validation logic.
