TDS polish: lt-frame tables, links search toolbar, dead CSS cleanup

- index.html: wrap UniFi devices table in lt-frame with section header
- links.html: add static lt-toolbar with lt-search filter and collapse
  controls above the dynamic container; remove collapse bar from
  renderLinks() since it's now static; add applyLinksSearch() to
  filter host/switch panels by name as user types
- suppressions.html: wrap Available Targets section in lt-frame
- style.css: remove unused .link-summary-panel and related rules
  (replaced by lt-stats-grid in previous commit)
