Replace undefined signed shifts in SPHlib SIMD FFT arithmetic with bounded multiplications, handle empty vectors in base64/base32/base58/hash/script paths, and skip the DoS_checkSig microbenchmark threshold under sanitizer instrumentation. Sanitizer ctest is now green locally, so make the GitHub sanitizer job blocking again.
