feat(bot): implement command registration system with GenerateCommand class

- Introduce `GenerateCommand` class:
  - Provides a unified mechanism to register bot commands dynamically.
  - Leverages `grammy` bot framework for command registration.

- Add `registerCommand` method:
  - Dynamically binds and registers command handlers from `GeneralCommands` and `UserCommands`.
  - Safely checks for the existence of a command handler before registration.
  - Uses the `bind` method to ensure the proper context (`this`) for command handlers.

- Add `generate` method:
  - Iterates over all command names defined in the `COMMANDS` array.
  - Registers each command by delegating to the `registerCommand` method.
