fix: correct production icon path and refresh icon cache on RPM install

- icon-manager.ts: fix production path from '../dist/public' to '../dist'
  Vite copies public/ assets to the root of dist/, not dist/public/, so
  the old path caused electronAppExists() to return null in packaged
  builds — falling through to Electron's default icon in the taskbar
- rpm-after-install.sh: add gtk-update-icon-cache and
  update-desktop-database so GNOME/KDE picks up the installed icon and
  desktop entry immediately without a session restart
