Resolve log injection warnings (G706) by sanitizing inputs using `filepath.Clean` before printing in `log.Printf`. Fix G124 by adding missing Secure and SameSite attributes to HTTP cookies in the auth package. The earlier attempt introduced errors (like `path` instead of `securePath` and syntax errors in `SameSite`).
