chore: reorganize icons for environment-specific deployment

Move environment-specific icons into dedicated directories (icons/develop, icons/test, icons/production) and update release scripts to copy the appropriate icon set (favicon.ico, Icon-192.png, Icon-512.png) into public/ for each target environment. Update manifest.json to reference the new /images/icons/ path.
