Search: refactor into modular helpers, add IP/hostname/notification/
vendor/model/type search, smart auto-redirects for exact matches,
ServiceNOW prefix detection, filter buttons with counts, share links
with highlight support, and dark mode badge colors.
Map: fix N+1 queries with eager loading (248->28 queries), switch to
canvas-rendered circleMarkers for better performance with 500+ assets.
