Replace the runtime-sized stack array in the spectrum processing path with std::vector to avoid compiler VLA extensions. Although the spectrum template is not instantiated as part of the current SDRangel build, GCC still emits -Wvla warnings while parsing the template definition. This change removes those warnings and keeps the template valid for future use. Use std::copy() and vector::data() when accessing the underlying storage.
