Merge type-only schema files (country_code.graphql, pagination.graphql,
identity.graphql) back into base.graphql for both trust/v1 and console/v1.
These standalone files had no corresponding _resolvers.go files, causing
gqlgen v0.17.87's Rewriter.getSource() to panic with 'slice bounds out
of range' when running go generate. By consolidating them into
base.graphql (which already has base_resolvers.go), gqlgen can process
the schema without needing separate resolver files for pure-type
definitions.
