Fix GTFS Flex feed detail map defaulting to bounding box when feed has no routes

[Copilot]

GTFS Flex feeds can have zero routes. When routes.json loads successfully but returns an empty array, CoveredAreaMap was staying on gtfsVisualizationView and rendering a blank map instead of falling back to the bounding box.

Changes

• CoveredAreaMap.tsx: Added selectGtfsDatasetRoutesTotal selector and a hasNoRoutes derived boolean (status === 'loaded' && total === 0). Both the view-determination effect and enableGtfsVisualizationView memo now treat an empty-routes load the same as a failed load — falling back to boundingBoxView and disabling the visualization toggle.

const hasNoRoutes = routesJsonLoadingStatus === 'loaded' && routesTotal === 0;

// view effect
if (feed?.data_type === 'gtfs' && routesJsonLoadingStatus != 'failed' && !hasNoRoutes && boundingBox != undefined) {
  setView('gtfsVisualizationView');
  return;
}
setView('boundingBoxView');

// toggle button enablement
const enableGtfsVisualizationView = useMemo(() =>
  feed?.data_type === 'gtfs' && routesJsonLoadingStatus != 'failed' && !hasNoRoutes && boundingBox != undefined,
  [feed?.data_type, routesJsonLoadingStatus, hasNoRoutes, boundingBox]
);

@copilot CoveredAreaMap component should get it's route data passed as a prop and not rely on the store

[Copilot]

Done in bfe0896. Added totalRoutes?: number to CoveredAreaMapProps and replaced the selectGtfsDatasetRoutesTotal store selector with the prop-derived value. FeedView (which already receives totalRoutes from the server-side fetch) now passes it down to CoveredAreaMap. The hasNoRoutes boolean is now computed as totalRoutes !== undefined && totalRoutes === 0.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Ran it locally and it works for the feed /feeds/gtfs/mdb-3081

[Alessandro100]

To test visit: https://mobilitydatabase-web-git-copilot-gtfs-flex-82520f-mobility-data.vercel.app/feeds/gtfs/mdb-2290 (a flex feed). Zoom out with your mouse on the map. For this ticket it fixes it in the sense that the detailed map doesn't show up, but another issue arrises with flex feeds -> the bounding box is a point instead of a box (at least for that feed)
