Refactor bot initialization and service registration for improved modularity

- Integrated new service building functions to streamline bot initialization, enhancing maintainability and clarity.
- Updated the dispatcher setup to include core services dynamically, reducing redundancy in service registration.
- Added support for multiple broadcast targets in the admin handler, allowing for more flexible message distribution.
- Enhanced localization for new broadcast target options, improving user experience in both English and Russian.
- Implemented new database access methods to retrieve user IDs based on subscription status, optimizing broadcast logic.
