Branding: Hash Wallet → Hash Bags for Windows + Linux app name

Final public name is Hash Bags (Such Software). iOS CFBundleDisplayName
and Android app.properties (generated by scripts/android/app_env.sh) were
already on Hash Bags; this catches the two remaining user-facing places:

  - env.json CW_WIN_APP_NAME (Windows launcher label)
  - linux/com.suchsoftware.HashWallet.desktop Name= (Linux app menu label)

Bundle IDs, Dart package name, and the .desktop file's app-id all stay
on hashwallet — those are internal identifiers that nobody sees.
