Replaces the QProcess->7z shim with the public-domain LZMA SDK (23.01) 7-Zip reader, vendored under sources/import/edz/lzma/ (decode-only subset). New edzsevenzip.cpp wraps SzArEx_Open/SzArEx_Extract and writes entries via Qt, so EdzArchive no longer needs an external 7-Zip at runtime. Enables the C language in CMake for the vendored sources. Verified: the bundled decoder extracts all three ifm sample .edz and the generated elements still match the Python oracle exactly (byte-correct decode), with no 7z on the path.
