Refactor command registration and service configuration

Refactored `Program.cs` to use new command registration method.
Moved `RegisterCommands` from `BotBuilder` to `ServiceCollectionExtensions`.
Updated `ServiceCollectionExtensions` to include `RegisterCommands`.
Added `AddDbContext` and `UseAuthorizationHandler` to services.
