Restore GraphQL schema merge for Relay query text

relay-compiler requires a single schema file: a directory is rejected
and schemaExtensions marks fields as client-only, so it emitted
text: null and the console posted query: null, getting a 400 on every
operation.

Restore the merge step (contrib/merge-graphql-schema.sh, the
RELAY_SCHEMAS make rules, and the gitignore entry) and point each
relay.config.json project back at the merged schema.graphql. The IDE
graphql-config removal and npm-script cleanup are unrelated and stay.

-`make relay` runs `relay-compiler`, which reads the split `.graphql` schema files directly (via each project's `schema` + `schemaExtensions` in `relay.config.json`) and keeps generated artifacts in sync (stale ones are removed automatically).
+`make relay` merges each service's split `.graphql` schema files into a single `schema.graphql` (via `contrib/merge-graphql-schema.sh`) and runs `relay-compiler`. The merge is required: relay-compiler's `schema` must be a single file, and `schemaExtensions` would mark the fields as client-only (emitting `text: null`), so the split files cannot be fed to Relay directly.
