Introduce useLocationMarker hook to manage a Leaflet marker (create, update and bind a popup). MapView now uses the hook and, when visible, requests navigator.geolocation to place/center a marker at the user's current position with a popup showing coordinates. Also includes a small indentation/whitespace cleanup.
Rename AzureAiService resource keys and app settings to AzureCognitive across the launcher. Updated Properties/Resources.Designer.cs to use AzureCognitive* properties, changed Resources.resx keys and the service prefix value, and updated app.config appSettings keys accordingly. Also adjusted editor.html to use the new setting names and user-facing "Azure Cognitive" wording and updated how the chat completions URL is constructed to use the AzureCognitive* settings.
Integrate a Leaflet-based MapView into the editor UI: load Leaflet CSS/JS resources, add a MapView React component (initializes map, OpenStreetMap tiles, cleanup on unmount, and calls invalidateSize when shown), and wire a new Map button into the ribbon to toggle map visibility. Add show/hide handling for the Editor component (toggle display via a visible prop) and manage map/editor layout by rendering them side-by-side and toggling display. Rename Azure AI references to Azure Cognitive (handler and button id/label) and update related prop names. Minor resource list and styling updates for layout and dependencies.
