feat: add http, snmp, docker plugins; new widgets and routes for traefik/unifi/ups

- Add HTTP monitor plugin: endpoint checking with status history, latency tracking, time-range views
- Add SNMP plugin: OID polling, device management, metric recording
- Add Docker plugin: container status, resource usage, widget
- Traefik: access log widget, request chart widget, expanded routes
- UniFi: clients widget, devices widget, expanded poll routes
- UPS: history widget, additional routes
- Update plugin index with new entries
