- /api/devices now groups hosts by deviceType tag instead of host group;
hosts without the tag are skipped
- /api/detail device lookup filters by deviceType tag instead of groupid
- getTag() is now case-insensitive on the tag name
- Removed selectHostGroups from fetchKFCData (no longer needed)
- Frontend: hex id and Zabbix deep-link use deviceType instead of groupid
- Smaller hex label (1.2rem) for device type view via hex-item--device class
- Skip DOM re-render on auto-refresh when data is unchanged (lastDataKey diff)

Skip the full-page loading state on background refreshes (only show it
on first load or view switch). Replace per-column requestAnimationFrame
appends with a single DocumentFragment swap so the browser never paints
a blank container between clear and insert.
