fix: resolve all lint issues across backend, WAF, and tests
- Fix 30+ errcheck violations in test files (db.Exec, QueryRow.Scan, json.Decode, os.WriteFile returns now explicitly handled) - Fix ineffassign in auth_test.go and waf heuristics_test.go - Bump version to 3.4.2 All components now pass golangci-lint with zero issues.
