build 394 — commit 1c25d1c

• import large ESRI shapefiles and GeoJSON datasets, including partial zip imports, converting to GPX and persisting generated files with metadata
• shared route import API/service/togpx pipeline with hardened GPX parsing, AWS upload normalization, WGS84 consistency, and organized GPX/ESRI asset structure
• expand map editor and viewer with palette-driven route styling, marker management, preview overlays, and route controls
• viewport-based filtering with dynamic refresh on pan/zoom, pre-calculated track bounds, 500-track fallback, and separate per-route rendering
• per-route “X of Y in view” counts using routeVisibleCounts, removing shared counters and unused properties, with improved badges and progress indicators
• performance logging for route processing and viewport intersections during GPX parsing
• search filtering for imported routes by name or description (case-insensitive), combined with viewport filtering, including match counts and UI controls
• functional refactors (map/filter), model consolidation, formatting cleanup ahead of phase 3, and updated Node requirements
• Bump default memory to 512mb to avoid OOM problems on failed deployment
