feat: enhance login process with IP capture and improved error handling

- Implemented an internal mutation for login that captures the user's IP address and user agent for better security and tracking.
- Enhanced the HTTP login endpoint to extract and log client IP, improving the overall authentication process.
- Added validation for IP addresses to ensure only valid formats are recorded, enhancing data integrity.
- Updated the login mutation to handle rate limiting and user status checks more effectively, providing clearer feedback on login attempts.
