Introduces new routes under /minecraftservices and /mojangapi for profile, skin, cape, blocklist, privileges, and certificate management. Adds a comprehensive userService module to handle user-related operations, and extends userRepository with methods for username changes, skin/cape management, blocking, and profile lookups. Refactors username availability logic into authService, updates error handling, and improves logger and utility functions. Also updates route handlers to use consistent return statements and enhances route registration logging.
Introduces a custom AccountsAPIError class for consistent error handling and serialization. Adds a new /productvoucher/giftcode route that returns a 404 error response for unimplemented endpoints.
Introduces two new routes: one for serving public keys from the certificates manager at /minecraftservices/publickeys, and another for listing blocked servers from the sessions service at /sessionsserver/blockedservers. These endpoints provide necessary data for authentication and server validation processes.
