MapViewer destroys and recreates the map when basemap changes. The readiness polling now detects when custom sources are missing (new map instance) and resets appliedSirutaRef + prevCheckSirutaRef, which triggers all effects to re-run: siruta filter, enrichment overlay, boundary mismatch GeoJSON, and fitBounds.
