- Added notifications for successful payments in `api/core/notifications.py`. - Created main API entry point in `api/main.py` with FastAPI integration. - Established routing structure in `api/routes/__init__.py` and `api/routes/pally.py` for handling payment callbacks. - Developed billing handlers in `bot/handlers/billing.py` and `bot/handlers/buy.py` for subscription management. - Introduced state management for user interactions in `bot/states/`. - Created user interface elements in `bot/keyboards/` for navigation and payment processing. - Set up middleware for dependency injection in `bot/middlewares/di.py`. - Added support for user commands and interactions in `bot/handlers/common.py` and `bot/handlers/support.py`. - Implemented logging and error handling throughout the bot's functionality. - Created entry point script for API server in `entrypoints/api.sh`.
