installer-rp: site-configured outputPackName for built zip

Adds a new "생성되는 리소스팩 이름" admin field saved to the pack
manifest and consumed by the rp installer when naming the final zip.
Empty value falls back to <packKey>_musicquiz; Windows-invalid chars
are sanitized to '_'. Bumps version 0.1.1 → 0.2.0 (new feature).
