feat: implement role-based access control for miniapp

- Introduced a new roles table in the database to manage user roles ('user' and 'admin') for access control.
- Updated the user model to include a foreign key reference to the roles table, allowing for role assignment.
- Enhanced command handlers to support the `/set_role` command for admins to assign roles to users.
- Refactored access control logic to utilize role checks instead of username/phone allowlists, improving security and maintainability.
- Updated documentation to reflect changes in access control mechanisms and role management.
- Added unit tests to ensure correct functionality of role assignment and access checks.
