fix: runtime fixes for service model and paginated responses

- Service.fromJson: string status/location enums, ISO8601 time parsing, additional_address field name
- _loadServices: unwrap {data:[...]} paginated response; extract embedded user from response instead of extra API calls
- calendar_services_provider: same response unwrap; fallback user when not embedded
- Add ProState import where needed
