- Add strictScalars: true to codegen.ts with proper scalar mappings
(Date, Decimal, JSONString, JSON, UUID, BigInt → string/Record)
- Replace all ref<any[]> with proper GraphQL-derived types
- Add type guards for null filtering in arrays
- Fix bugs exposed by typing (locationLatitude vs latitude, etc.)
- Add interfaces for external components (MapboxSearchBox)
This enables end-to-end type safety from GraphQL schema to frontend.
