fix: correct environment issues doc and add missing config improvements

- Remove fabricated etcd/Kafka/AWS issues from TEST_ENVIRONMENT_ISSUES.md
  (codebase contains zero references to these dependencies)
- Add Kafka/etcd/CloudWatch clarification: early design docs discuss
  these but actual implementation uses none of them
- Add getEnvInt() for GATEWAY_PORT env variable support
- Add devtest stack scripts for local development
- Update verification report and repair plan status
