Implement extension request and gift functionalities in billing system

- Added new endpoints for creating and managing extension requests, allowing users to request billing period extensions. - Implemented admin approval processes for extension requests via Telegram, including inline buttons for approval and rejection. - Introduced a gifting feature for admins to grant additional billing days directly to users without a request. - Updated the support ticket model to accommodate extension requests and their associated properties. - Enhanced the Telegram notifier to inform admins of new extension requests and notify users of approval or rejection. - Updated frontend components to support the new extension request and gifting functionalities, including user interfaces for managing these features. - Revised API documentation to reflect the new endpoints and their usage in the billing context.
