zwitschi 0f076205af Fix NSIS installer build: absolute paths via defines, space-free installed exe, BMP ICO ...

- makensis resolves relative -DICON/-DARTIFACT against the script directory,
  so CI now passes $PWD-based absolute paths (reproduced locally in the same
  ubuntu:24.04 container; installer builds, 7z shows step-line.exe +
  uninstall.exe)
- Install as step-line.exe (no spaces: NSIS /oname splits on whitespace)
- OutFile overridable via -DOUT
- tools/generate_textures.py icon.ico now produced via ImageMagick with
  classic BMP entries (NSIS-compatible); PIL PNG-compressed ICOs rejected by
  NSIS
