luyao618 b4b8509fe8 fix(gateway): load streaming config from nested gateway.streaming key
`hermes config set gateway.streaming.*` writes the streaming block
nested under a `gateway:` key in config.yaml, but the config loader
only checked for a top-level `streaming:` key — silently ignoring
the nested variant.

Fall back to `yaml_cfg['gateway']['streaming']` when the top-level
key is absent, matching the pattern already used for other nested
config sections.

Closes #25676
