Add a grouped tag+node search endpoint for the upcoming dashboard

AdminController#dashboard_search returns tags and nodes as separate,
labeled groups (via ActsAsTaggableOn::Tag.named_like and
Node.editor_search) rather than the flat per-node list every existing
picker returns. initSearchPicker gains a renderResults callback option
that, when given, replaces the default per-node rendering entirely --
lets the dashboard render its two labeled groups without a second,
parallel picker implementation.

resultsHeaderHtml (the "Press Enter to see all results" hint) is now
threaded through as a third argument to renderResults, so a picker with
custom rendering can still show it -- previously only the default
per-node branch ever did.

Tags link straight to the existing /admin/nodes/tags/:tag view rather
than becoming an in-place filter chip.
