Bot for administering a closed club in Telegram

Bot functionality:
Payment is made directly in the bot thanks to integration with payment services (WayforPay and others).
The system allows checking the presence of payment and automatically granting or restricting access.
A notification system is set up to remind the user about the expiration of the subscription.
All information about the Club is moved to a separate section.
The ability to ask questions through text input has been added. Notifications about new requests and payments are sent to the admin chat with a direct link to the dialogue.
The option to choose the subscription term has been implemented.
