feat(config parse): replace yaml value(int/float ) from env('KEY')

[Xiaoming-AMD]

enhance replace_env_variables: support numeric string auto-conversion

• Improved env var substitution logic to automatically convert numeric strings to int or float:
  • ${PORT:8080} → 8080 (int)
  • ${RATIO:0.75} → 0.75 (float)
• Used regex matching to detect and convert pure numeric strings after substitution.
• Ensures cleaner config loading when numeric values are passed via environment variables.
