Updated macOS bundle translation sources to use ${prefix}/locale for both GTK and ZoiteChat catalogs, preventing the bad .../ocale/...-style resolution path caused by prefix/path mismatch during bundling.

Updated both CI macOS staging jobs (arm64 and x86_64) to copy app-installed locale catalogs from $STAGE_PREFIX/share/locale into $STAGE_PREFIX/locale when present, so zoitechat.mo is available to gtk-mac-bundler in the staged tree.
