fix: direct namedTheme import fixes GeoJSON rendering, guard optional layer queries

Browse source 
Root cause: Vite's bundling of namedTheme through the registry re-export
broke MapLibre's Web Worker, silently preventing all GeoJSON rendering
(routes, boundaries, measure tool). Fixed by importing namedTheme
directly from protomaps-themes-base in MapView.jsx.

Also guards queryRenderedFeatures calls for optional overlay layers
(USFS trails, BLM roads) that may not exist in the current style.
