feat(rate-limiting): implement rate limiting for login attempts and enhance configuration

- Added environment variables for `RATE_LIMIT_MAX_FAILED_ATTEMPTS` and `RATE_LIMIT_LOCKOUT_TIME`
- Integrated rate limiting into the login process with a maximum of 5 failed attempts
- Refactored login attempt recording into the `authRouter`
- Removed deprecated `recordLogin` middleware and adjusted related logic
