Integrate test code improvements using web_template components

lt-alert:
- Replace custom .stale-banner with lt-alert lt-alert--warning in app.js
  and links.html; remove stale-banner CSS, reuse lt-alert margin rule

lt-progress:
- Replace custom .traffic-bar-track/.traffic-bar-fill in links.html with
  lt-progress from base.css; TX uses default (orange), RX uses --cyan,
  both flip to --red when utilisation >85% (trafficBarClass helper)
- Keep traffic layout classes (.traffic-section/.traffic-row etc.) for structure

Suppression type badges:
- Map target_type to distinct badge colors: host→badge-warning (orange),
  interface→badge-info (cyan), unifi_device→badge-purple (new alias using
  --accent-purple from base.css), all→badge-critical (red)
- Applied in both server-rendered table (Jinja2 dict lookup) and
  renderActiveRows() JS

Topology animated down-wire:
- Add data-host attribute to .topo-v2-wire-10g/.topo-v2-wire-1g elements
- updateTopology() toggles .wire-down class on the 10G drop-wire when
  host.status === 'down'
- .wire-down CSS: animated repeating-linear-gradient dashed red line
  via wire-dash-anim @keyframes
