…rification and a retry loop.

Description

1. Enhance: Improve initial password script robustness and reliability to ensure successful setup.
2. Fix: Prevent the password initialization job from completing prematurely when the StarRocks FE is not fully started, by implementing a blocking wait mechanism.
3. Refactor: Change FE connection strategy to use the standard Service address instead of the Headless Service.
