DRAFT: feat(Map): add OpenStreetMap (OSM) provider for dxMap

[AlisherAmonulloev]

Keyless, Leaflet-based OSM provider (provider: 'osm'). Tiles, geocoding and routing are supplied by the consumer via providerConfig.{tileServer, geocodeLocation, getRoute} rather than bundled, so no public OSM tile server is used by default. Adds errors W1030/W1031/W1032 for missing tile server, geocode callback and attribution.

• New provider implementation and Leaflet integration
• 'osm' added to MapProvider; providerConfig OSM types in map.d.ts
• Regenerated React/Vue/Angular wrappers and aspnet metadata enum
• React Storybook story (Map/OSM Provider)
• Unit tests with a Leaflet mock

Pull request overview

This PR adds a new provider: 'osm' option for dxMap, implementing an OpenStreetMap provider backed by Leaflet. It introduces OSM-specific providerConfig hooks (tiles/geocoding/routing provided by the consumer), integrates the provider into the core Map widget, updates typings/metadata/wrappers, and adds a Leaflet mock plus QUnit coverage and a React Storybook example.

Changes:

• Added a Leaflet-based OSM dynamic provider and hooked it into dxMap’s provider registry and option-change pipeline (incl. runtime tileServer updates).
• Extended public typings (MapProvider, OSM callback/types) and propagated the new provider to metadata and framework wrappers.
• Added QUnit test coverage for the new provider using a Leaflet mock, plus a React Storybook story demonstrating configuration.
