fix(demo): rebuild products_fg as clean products + productCount delta

[jvr545]

Summary

Rebuild products_fg subgraph to be a clean copy of products with only one addition: Employee.productCount: Int!

Changes

• Sync schema.graphqls with base products (restore @cost/@listSize directives, Thing type, sharedThings/slicedThings/searchThings queries)
• Remove junk comment # dwedwedew
• Add missing resolvers (SharedThings, SlicedThings, SearchThings)
• Fix employee ID 7 missing ProductCount value
• Regenerate gqlgen artifacts

Schema delta (products_fg vs products)

type Employee @key(fields: "id") {
  id: Int!
  products: [ProductName!]!
+ productCount: Int!
  notes: String @override(from: "employees")
}

Test plan

• go generate succeeds
• go build ./cmd/products_fg succeeds
• _entities query returns productCount: 5 for Employee id 1
• SDL includes all restored fields and directives

Deploy reminder

After merge, redeploy Fly app product-api-fs using demo/docker/products_fg.Dockerfile
