Dashboard: dynamic tag filters with counts + combined search

[hulki-bot]

Summary

This improves dashboard tile filtering UX by combining search + tag filters and adding dynamic tag button behavior.

What changed

• Move search UI above tag buttons on dashboard.
• Render tag buttons for both treat_tags_as=tags and treat_tags_as=categories.
• Add category class marker to category wrappers for reliable category filtering.
• Add dynamic tag button counts (TagName (n)) based on current tile-search context.
• Combine search text and selected tag filtering in tile mode.
• Improve filtered category rendering:
  • hide category titles while filtered,
  • hide category wrappers without matching children,
  • reset wrapper visibility each run to avoid multi-click stale-state issues.
• Add usage-based tag ordering with localStorage persistence:
  • keep All fixed first,
  • order remaining tags by frequency in the last 100 clicks window.
• Add defensive Sortable initialization guard to avoid JS runtime breaks when Sortable is unavailable.
