fix(ts-sdk): initialize sandboxId in RockEnv and use HttpUtils

- Add static factory method RockEnv.create() for async initialization
- Call 'make' API to get sandboxId during initialization
- Replace raw AxiosInstance with HttpUtils for consistent camelCase/snake_case conversion
- Update make() factory function to be async
- Add comprehensive tests for RockEnv
