fix: resolve remaining TypeScript errors

- Fix toast context usage in CategoryFormPage
- Add null checks for optional properties (product.price, product.status)
- Fix undefined checks for product_id parameters
- Add type assertion for PRODUCT_TYPE_LABELS indexing
- Fix number/string type conversions in ProductFilters
- Add proper type handling for form validation

All TypeScript compilation errors are now resolved
