[Build] Keep Windows installs free of build-tree artifacts

Several Windows packaging gaps could leak Visual Studio CMake build
output into the installed application or the NSIS installer:

- The per-app DLL sweep used
  ${CMAKE_BINARY_DIR}/${PROJECT_NAME}/${CMAKE_BUILD_TYPE}, which is
  empty on multi-config generators, collapsing the recursive
  DIRECTORY install into the whole build tree (containing *.dir,
  *_autogen, .qt, .qsb, x64, ...). Point it at the real per-config
  output with $<TARGET_FILE_DIR:...> and exclude build artifacts.
- install(FILES ${OPENSSL_INCLUDE_DIRS} ...) tried to install OpenSSL
  include directories as files. CMake refuses this
  ("install FILES given directory"); it only slipped through CI
  because the vcpkg OpenSSL config leaves the variable empty. Remove it;
  fixup_bundle already ships the OpenSSL runtime DLLs.
- The NSIS uninstaller only deleted *.exe/*.dll and a few known files,
  so build-tree leftovers survived an uninstall/reinstall cycle. Wipe
  the whole directory tree instead.
- Add a Windows CI gate that lists the packaged installer with 7-Zip
  and fails the build if any build-tree artifact path is found.
