feat(esm): Convert test infrastructure files to ESM

Converted critical test support files:
- test/data/graphql/index.js - GraphQL test server
- test/data/sandbox/support/bdd_helper.js - BDD test helper
- test/data/sandbox/workers-proxy-issue/*.js - Worker test files
- test/mock-server/server.js - Mock REST server
- test/mock-server/start-mock-server.js - Server startup script

These files are required for running the test suite.
