Fix CI build: add CUDA paths after vcvarsall, improve workflow

- build.bat: add CUDA_PATH/include and CUDA_PATH/bin to INCLUDE/PATH
  after vcvarsall.bat resets the environment (fixes cuda_runtime.h not found)
- workflow: add version detection step (from tag or version.h)
- workflow: pass version to ISCC via /D flag for consistent naming
- workflow: add DSD-FME verification step
- ISS: accept MyAppVersion override from CLI, keep default for local builds
