feat: Implement Steam login initialization logic

- Added SteamLoginInitLogic to handle the initiation of Steam login.
- Created service context for managing configuration and Redis connection.
- Defined types for Steam login requests and callbacks.
- Implemented utility functions for building OpenID query strings and validating responses from Steam.
- Updated go.mod and go.sum to include necessary dependencies.
- Modified GenApi.ps1 script to generate code in the correct directory.
