fix: InvalidClientTokenId panic + VT defaults + Dockerfile config + hardcore tests (58/61)

- Add InvalidClientTokenId, ValidationError to SqsErrors (was causing panic: WriteHeader code 0)
- Extract applyEnvironmentDefaults() with defer in LoadYamlConfig (VT=30 even without config file)
- Dockerfile: copy goaws.yaml to /conf/, pass --config flag
- Fix SendMessageBatch form parsing for AWS Query Protocol
- Add hardcore_test.sh (61 tests, 14 groups)
- Remove temp debug logs from delete_message.go
