Add TileProvision configuration and gRPC service for tile delivery

- Introduced new TileProvision settings in appsettings.json, including MaxTilesPerBatch and ProgressEmitIntervalSeconds.
- Configured TileProvisionConfig in Program.cs to bind the new settings.
- Added gRPC service for RouteTileDelivery in Program.cs to handle tile delivery requests.
- Updated SatelliteProvider.Api.csproj to include Grpc.AspNetCore package and added protobuf file for tile provision.
- Enhanced AuthenticationServiceCollectionExtensions to handle JWT token extraction from the Authorization header.
- Registered additional services in RouteManagementServiceCollectionExtensions for tile processing.

These changes enhance the API's capability to manage tile provisioning and delivery efficiently.
