tone3000: IR downloads, model detail, arch filter, metadata

- NAM/IR tab toggle in Downloads overlay
- Architecture filter (All/Nano/Feather/Standard) - filters via
  Supabase architecture_version column
- Model detail overlay: tap a search result to see full description,
  gear info, author, pack, architecture, thumbnail before downloading
- IR search + install with .meta.json metadata saving
- Backend: search_models/get_trending_models accept arch param
- Backend: tone_gear field added to model search response
