fix: AppImage packaging and branding corrections

- electron-builder.json: restore entry wrapper with full desktop fields
  (Comment, Name, Icon, Type, Categories, Keywords, etc.) required by
  electron-builder 26.0.x schema; add co.nineapp paths for extraFiles
- Rename com.nineapp.nine.appdata.xml -> co.nineapp.nine.appdata.xml;
  update internal <id> and <launchable> from com.nineapp to co.nineapp
- nine.desktop: mark as reference template (electron-builder generates its own)
- LinuxKeychainService: rename Schema constant from org.aquiis.database
  to co.nineapp.database
- Remove desktop-config.bk scratch file
