Integrate Data Completeness Dashboard

Adds comprehensive data completeness dashboard UI and hooks:
- Introduces data completeness types and hook (useDataCompleteness) to fetch and subscribe to updates
- Builds dashboard components (summary, filters, table) and integrates into Admin Settings
- Wireframes for real-time updates and filtering across parks, rides, companies, and ride models
- Integrates into AdminSettings with a new Data Quality tab and route
- Adds data types and scaffolding for analytics, including completeness analysis structure
