- manifest.json: keys reordered to domain, name, then alphabetical
- strings.json + translations/en.json: rephrase user-step description
without backticks/angle-brackets (hassfest rejects HTML in i18n strings)
- __init__.py: add CONFIG_SCHEMA = cv.config_entry_only_config_schema(DOMAIN)
since async_setup exists but the integration is config-entry-only
