WIP: Migrate calendar integration frontend to React Query

- Migrate all calendar components from useApi to React Query hooks
- Fix Chakra UI v3 compatibility issues (Card, Progress, spacing props, leftIcon)
- Update backend Meeting model to include calendar fields
- Replace imperative API calls with declarative React Query patterns
- Remove old OpenAPI generated files that conflict with new structure
