Expose the control plane OpenAPI spec at /v1/openapi.json

[bam4564]

Summary

• expose the Effect-generated control plane OpenAPI document from the local server
• serve it at /v1/openapi.json so it lines up with the current v1 API surface
• add a server regression test that boots a real local Executor instance and verifies the returned spec matches controlPlaneOpenApiSpec

Testing

• bun run --cwd packages/server typecheck
• bun run --cwd apps/executor typecheck
• bun run --cwd apps/executor test -- src/server/server.test.ts -t "serves the control-plane OpenAPI spec at /v1/openapi.json"
