fix: Add Apple Silicon (M1/M2/M3) compatibility support for LabRecorder

This commit enhances the macOS build process to properly support Apple Silicon processors by:

1. Detecting arm64 architecture during the build process
2. Fixing Qt plugin path references on Apple Silicon to use @executable_path instead of @rpath for proper library loading
3. Implementing a thorough code signing process that handles component level signing for Frameworks and PlugIns

These changes address the reported issues with missing dependencies(libbrotlicommon.1.dylib) and code signing errors that prevented LabRecorder from running on Apple Silicon Macs.
