fix(auth): ensure telegramId is a string for consistent handling

- Updated the signIn calls in both Auth and useAuth functions to convert telegramId to a string.
- Modified the JWT callback to store telegramId as a string in the token.
- Enhanced session handling to correctly assign telegramId from the token to the session user.
- Added type definitions for telegramId in next-auth to ensure proper type handling.
