refactor: update app code for domain-scoped schema migration

- Update dbt model references to use new schema naming (stg_toronto, int_toronto, mart_toronto)
- Refactor figure factories to use consistent column naming from new schema
- Update callbacks to work with refactored data structures
- Add centralized design tokens module for consistent styling
- Streamline CLAUDE.md documentation
